FEATURES:
The PSL+ ™ Programmable Security Lock is an enhanced version of the PSL ™ product with
several additional features. Like the original, this version is primarily designed for use with both
battery and I.C. engine powered vehicles to prevent unauthorized operation of the vehicle.
Expanded Voltage Range
- The PSL+ is rated for nominal input voltages from 12 to 90VDC.
Expanded User Capability
The PSL+ can be programmed for up to 99 unique users. Once installed, the PSL+ requires entry of a two-
digit user number and valid four-digit access code before the vehicle or equipment can be operated. All user
codes can be reprogrammed and unused user numbers can be temporarily disabled for additional security.
Last User Identification
The PSL+ can identify to the supervisor the user number of the last user of a vehicle.
Automatic Shut-Off
The PSL+ incorporates a feature that detects vehicle activity. If the vehicle has been inactive
beyond a specified period of time, the PSL+ will deactivate securing the vehicle. This feature is
optional and can be activated or deactivated as desired.
Maintenance Alert
The PSL+ can accumulate vehicle usage time and provide audible and visible signals indicating when
vehicle maintenance is due. After maintenance is performed, the cycle can be reset as desired. This
feature is optional and can be activated or deactivated by supervisor.
Accumulated Time
The PSL+ accumulates total vehicle usage time. This accumulated time can be accessed through
the Supervisor Code.
Even the supervisor’s access code can be changed using the factory programmed reset code.
Installation of the PSL+ remains simple with just 4-5 wires to connect. Diagrams showing typical
wiring schemes are included in this manual.

WARRANTy NOTE
The PSL+ is a sealed unit. There are no user serviceable parts inside. Removing or tampering with
the epoxy encapsulant will void the warranty.
Upon installation of the PSL+, the unit must first be programmed with a supervisor code. When the
unit is first powered up, or powered up for the first time after executing a reset procedure, it will
automatically go into supervisor code programming mode. This mode is indicated by alternately
displaying 3 amber flashes and 3 red flashes. When in this mode, simply enter the four digits you
would like to use as the supervisor access code. You must use all numerical digits; the “on” and
“off” keys may not be incorporated into the supervisor code. All combinations of numerical digits
are acceptable except 0000. For best security, we recommend avoiding repetitive digits like 4444
and sequential digits like 1234. You will hear a short beep to acknowledge each key entry. If an
illegal character is selected, an error beep consisting of a short beep followed by a long one will be
sounded. If this occurs, you must continue from the point prior to the illegal character being pressed
or remove power and start the code entry process over. When an acceptable 4-digit supervisor code
has been entered, the amber “accept” LED will be illuminated and the unit will stop responding. At
this point the new supervisor code has been programmed and the unit must be powered down to
allow for normal start up before proceeding. It may be a good idea to write down the supervisor
code and keep it in a safe place so you don’t forget it, but if you do the supervisor code can be reset
and reprogrammed (See page 10). Note: If an undesired key is entered during supervisor code
entry, the procedure can be aborted by removing power from the unit.
Quick Steps – Supervisor Programming
1. Enter desired 4-digit supervisor code. Unit will beep with each key depression.
2. Power down unit to save code.
Entering Supervisor Mode is necessary for configuration of programmable settings and retrieval
of data stored in the PSL+. The procedure for entering supervisor mode is a simple two step
process. Each key entry is acknowledged with a short beep and errors are indicated with the short
+ long beep pattern. Keystrokes are timed with a limit of 15 minutes between keystrokes or the
process will be aborted. The process may also be aborted manually by pressing “off”. The output
must be off before beginning this procedure:
1. Enter “00”. This identifies you as the supervisor.
2. Enter the four-digit supervisor code. Upon completion the entry is checked. If the entry is
correct, the amber “accept” LED will acknowledge the entry and then the red and amber LEDs
will begin to flash alternately to indicated the unit has entered supervisor mode. If incorrect,
the error beep is sounded and the process aborted.
Quick Steps – Entering Supervisor Mode
1. Enter “00”.
2. Enter four-digit supervisor code. The “accept” LED will acknowledge the entry and then the red
and amber LEDs will begin to flash alternately to indicate the unit has entered supervisor mode.

Using External Relay for High Current Load with No Activity Monitoring
After installation and set up of the PSL+, the unit should be checked for proper operation under
normal vehicle operating conditions. If automatic shut-off function has been activated, it is
imperative that this function be tested after installation. This is why it is suggested to set a short
shut-off time delay until correct operation of this function has been verified. A recommended test
procedure would be to raise the drive wheels and operate unit for a period of time greater than
the automatic cut-off time. During this period, the PSL+ should not deactivate the vehicle under
any circumstance. After exceeding the ASO period, leave the vehicle in non-active mode (seat
switch inactive, etc.). After the automatic shut-off period has expired, the PSL+ should deactivate
automatically. If the unit operates as described, the PSL+ ASO function has been installed
correctly. At this point, the desired ASO delay time can be configured as desired through
supervisor Function 4.

This mode is used to program user codes and set up advanced functions of the PSL+. From this
mode each key initiates a specific configuration procedure or function in the supervisor menu.
These options are explained one by one in the following sections and listed in the table below.
Supervisor Function Menu
Function 1 Allows programming of up to 99 unique user codes
Function 2 Displays last user of vehicle
Function 3 Activates/deactivates automatic shut-off
Function 4 Sets automatic shut-off time delay
Function 5 Enables maintenance cycle counter
Function 6 Sets maintenance cycle activation mode
Function 7 Sets maintenance cycle period
Function 8 Sets frequency of maintenance reminder tone
Function 9 Allows display of maintenance and accumulated times
Function 0 Resets maintenance cycle
Function 1 – User Programming
The “1” key initiates user code programming mode. When you press the “1” key, the red “program”
LED will begin flashing to indicate the unit has entered user code programming mode. To program
a user code, follow the two step procedure below. Like the supervisor code, user codes must
consist of four numerical digits and may not include “on” or “off” keys. If you wish to disable a
user number, then program its access code to 0000. All user numbers are disabled initially and
remain disabled until programmed using this function. You may abort the entry procedure at any
time and return to supervisor mode by pressing the “off” key.
Step 1: Enter the two-digit user number. User numbers must be two digits so those numbers
less than 10 must be entered as “01”, “02”, etc. When you have entered a (valid) user
number, the red “program” LED will stop flashing and stay on indicating the unit is ready
for you to enter the new access code.
Step 2: Enter a four-digit user access code. Upon completion of the entry of a valid access
code, the amber “accept” LED will be illuminated for one long flash and then the unit
will go back to supervisor mode.
Quick Steps – Function 1
1. While in supervisor mode press1. Unit will indicate Function 1 configuration mode active.
2. Enter two-digit user number followed by four-digit access code. Amber LED will indicate
acceptance of code and unit will return to supervisor mode.
Function 2 – Last User Identification
The “2” key initiates the last user function. This function will tell you which user number was the
last one to activate this unit. If the supervisor was the last one to turn on the output, then an error
signal (short then long tone) beep will sound and the unit will go back to supervisor mode.
III. SUPERvISOR MOdE:

Otherwise, the unit will sound four short beeps to indicate the last user information is coming
followed by a series of flashes of the red and/or amber LEDs. Each red flash counts as 10 and
each amber flash counts as one. For example, if user 27 were the last one to activate the unit,
you would see 2 red flashes followed by 7 amber flashes. Upon completion of the flashes there
will be about a ¾ second pause, and then the unit will return to supervisor mode. You may repeat
this procedure as many times as you wish if you want to make sure that you counted the flashes
correctly.
Quick Steps – Function 2
1. Press 2. Unit flashes last user code (red=10, amber=1, i.e. user 37 would be displayed as
3 red flashes and 7 amber flashes) and unit returns to supervisor access mode after displaying
user code.
Function 3 – Automatic Shut Off
The “3” key initiates a procedure to enable or disable the Automatic Shut Off (ASO) function.
Entry into this mode is signified by a flash cycle consisting of 1 amber flash followed by 3 red
ones. (Note that the number of red flashes corresponds to the supervisor menu selection.)
In this mode the “on” key enables the automatic shut off function and the “off” key disables it.
Pressing any other key will generate an error signal (short then long tone) and the procedure will
be aborted returning you to the supervisor mode. If you are disabling the ASO function, a single
long flash of the amber “accept” LED will acknowledge the change and then the unit will go back
to supervisor mode. The default setting for the ASO function is disabled so you only need to worry
about this procedure if you want to use this function. The default delay time is 5 minutes. (This
may be changed using Function 4.)
The ASO function monitors the vehicle through the blue wire that is known as the Vehicle Status
Input (VSI). Typically, this wire would be connected to a seat or foot switch so the unit can tell
when the vehicle or equipment is being left unattended. Due to the number of different possible
wiring configurations (switch to ground, switch to B+, normally open, normally closed, etc.), the VSI
input must be configured when the first function using it is enabled. If the VSI input has already
been configured for the maintenance cycle function, the unit will acknowledge your entry and
return to supervisor mode when the ASO function is enabled. Otherwise, it will automatically go
into the Vehicle Status Input configuration procedure (described on Page 8-9). This procedure
must be successfully completed or the ASO function will not be enabled.
Quick Steps – Function 3
1. While in supervisor mode press 3. Unit will indicate Function 3 configuration mode active.
2. Depress the “on” key to activate automatic shut off. Amber indicates selection acceptance. Unit
returns to supervisor access mode after selection if VSI is already configured or goes to 3 if not
OR
Depress the “off” key to deactivate automatic shut off. Amber indicates selection acceptance. Unit
returns to supervisor access mode after selection.
3. Set up VSI – See VSI Configuration Instructions (described on Page 8-9)

The PSL+ utilizes the same basic package as the original PSL product and may be mounted with
the hardware provided in most any accessible flat location where you can put the required mount-
ing holes. As mentioned earlier, the PSL+ has five color-coded lead wires. The functions of all five
wires are listed below and several wiring diagrams for typical applications are included.
Black – The black wire is connected to ground (B-).
Red – The red wire is connected to B+.
Orange (2) – The orange wires are the output. When the output is turned on, they are connected together by
an internal relay. When the output is off, they are disconnected. The maximum current through
these leads is 10 amps. If you wish to control a load, which draws more than 10 amps, you
must use these leads to control an external relay or contactor, which in turn controls the actual
load. In 48V and above applications, maximum relay current should not exceed 1 amp.
Blue – The blue wire is the VSI (Vehicle Status Input) used to control the automatic shut off function
and the maintenance cycle function if so configured. If you are not planning to use these
features, then the blue wire does not need to be connected.

Previously programmed users may activate the output of the PSL+ by following the three-step
procedure below. All key entries in this process are acknowledged with a short beep and are
timed to protect against the user leaving the unit with a partially entered access code. If a period
of 15 minutes elapses between keystrokes, the unit will abort the procedure and sound an error
beep. The entry process may also be aborted manually at any time by pressing the “off” key. The
three-step process is as follows:
Step 1: Enter the two-digit user number. (All user numbers must be two digits, i.e. “01”, “02”, etc.)
Step 2: Enter the four-digit access code for that user. Upon completion, the entry is checked and
the amber “accept” LED is illuminated if the entry is correct. If the entry is incorrect, then
the error beep is sounded and the entry procedure is aborted.
Step 3: Press the “on” key. The “accept” LED will go off and both the output and “on” LED will be
activated. Press the “off” key or remove power to turn the output off.
Follow the procedure below to reset the supervisor code. This process may be aborted at any
time during the procedure by pressing the “off” key. The output must be off before beginning this
procedure. Using this procedure to reset the supervisor code will NOT affect any programmed user
codes or any of the function settings.
Step 1: Enter “00”. This identifies you as the supervisor.
Step 2: Enter “0000”. After entering the sixth zero, the unit will begin alternately flashing the
amber LED twice and the red LED twice to indicate reset code entry mode.
Step 3: Enter the four-digit reset code. If the correct code is entered, the unit will acknowledge
the entry with one long flash of the amber “accept” LED and then power must be
interrupted before proceeding. The unit will automatically go into the supervisor code
entry mode (as described in Part 1) when power is restored. If an incorrect reset code is
entered, then the error beep will sound and the unit will go back to access code entry
mode (the supervisor code will not be reset).

Function 4 – ASO Delay Time
The “4” key initiates a procedure to set how long the Automatic Shut Off (ASO) function will wait
after the Vehicle Status Input (VSI) input becomes inactive before shutting off the output. Entry
into this mode is signified by a flash cycle consisting of 1 amber flash followed by 4 red ones. You
may change this setting whether or not the ASO function is enabled however it has no effect until
it is enabled. Settings are retained if the ASO function is disabled, and then enabled again at a
later date. You may set the delay in one minute increments from 1 to 999 minutes (16.5 hours),
but all entries must be 3 digits (Example: 1 minute = 001, 10 minutes = 010, etc.) Each digit
entered is acknowledged with a short beep. Once the third digit has been entered, the unit will
save the setting and acknowledge that fact with a long flash of the amber “accept” LED and return
to the supervisor mode. Pressing the “on” key during this process will generate an error signal
(short then long tone) and the procedure will be aborted, returning to supervisor mode. You may
manually abort the process and return to supervisor mode by pressing the “off” key. The default
setting for the ASO delay time is 5 minutes. For safety reasons, we recommend setting the delay
for 1 minute and testing to make sure everything operates as intended before setting the desired
shut-off delay.
Quick Steps – Function 4
1. While in supervisor mode press 4. Unit will indicate Function 4 configuration mode active.
2. Enter 3-digit delay time in minutes (i.e. 120 minutes = 120). Pressing “on” produces error and
returns to supervisor mode; pressing “off” aborts procedure and returns to supervisor mode.
3. Unit returns to supervisor mode after valid 3-digit input.
Function 5 – Maintenance Cycle Enable/Disable
The “5” key initiates a procedure to enable or disable the Maintenance Cycle (MC) function. Entry
into this mode is signified by a flash cycle consisting of 1 amber flash followed by 5 red ones. In
this mode, the “on” key enables the MC function and “off” key disables it. Pressing any other key
will generate an error signal (short then long tone) and the procedure will be aborted, returning
you to supervisor mode. A single long flash of the amber “accept” LED will acknowledge the
new setting and then the unit will go back to supervisor mode. New units start with 1000 hours
remaining in the MC unless changed with Function 7. Units that previously used the MC cycle will
revert to the point where they were when the MC function was last disabled. Activating the MC
function does NOT reset the cycle. The default setting for the MC function is disabled so you only
need to worry about this procedure if you want to use this function.
Quick Steps – Function 5
1. While in supervisor mode press 5. Unit will indicate Function 5 configuration mode active.
2. Press “on” to enable maintenance cycle or press “off” to disable maintenance cycle.
Note: Pressing any other key than “on” or “off” aborts process and returns unit to supervisor
mode.

Function 6 - Maintenance Cycle Activation Control
The “6” key initiates a procedure to set whether the Maintenance Cycle (MC) function is controlled
internally (time accumulates whenever the output is on) or externally (time accumulates only if the
output is on AND the Vehicle Status Input (VSI) input is active). Entry into this mode is signified
by a flash cycle consisting of 1 amber flash followed by 6 red ones. In this mode, the “1” key sets
the MC function control to internal and the “2” key sets it to external. Pressing any other key will
generate an error signal (short then long tone) and the procedure will be aborted, returning you to
supervisor mode. If you are setting the MC control type to internal and/or the Automatic Shut Off
(ASO) function is enabled, a single long flash of the amber “accept” LED will acknowledge the new
setting, and then the unit will go back to supervisor mode. If the ASO function is disabled, and
you are setting the MC control to external, then the unit will automatically go into the VSI
configuration procedure (described on Page 8-9) which must be completed successfully or the
change will not be saved. The default setting for the MC control is internal.
Quick Steps – Function 6
1. While in supervisor mode press 6. Unit will indicate Function 6 configuration mode active.
2. Press 1 to set maintenance counter to internal. Amber LED will indicate acceptance of selection
and unit will return to supervisor mode. Maintenance time will subsequently accumulate when
ever PSL+ activates vehicle.
Or
Press 2 to set maintenance counter to external mode. Maintenance time will Accumulate only when
Vehicle Status Input is active. Note: If Vehicle Status Input was not previously configured, unit will
immediately enter the VSI configuration procedure. (See instruction on Page 8-9 of manual.)
Note: Pressing any other key than “1” or “2” aborts process and returns to supervisor mode.
Function 7 – Maintenance Cycle Period
The “7” key initiates a procedure to set the maintenance cycle time. Entry into this mode is
signified by a flash cycle consisting of 1 amber flash followed by 7 red ones. You may change this
setting whether or not the Maintenance Cycle (MC) function is enabled, but if not it won’t have
any effect until that function is enabled. Settings are retained if the MC function is disabled and
enabled at a later date. You may set the maintenance cycle time in one hour increments from
1 to 9999 hours (14 months if running 24/7), but all entries must be 4 digits (Example: 1 hour
= 0001, etc.). Each digit entered will be acknowledged with a short beep. Once the fourth digit
has been entered the unit will save the setting and acknowledge that fact with a long flash of the
amber “accept” LED and then return to the supervisor mode. Pressing the “on” key during this
process will generate an error signal and the procedure will be aborted, returning to supervisor
mode. You may manually abort the process and return to supervisor mode by pressing the “off”
key. A new cycle is started automatically when the MC time is changed.
Quick Steps – Function 7
1. While in supervisor mode press 7. Unit will indicate Function 7 configuration mode active.
2. Enter 4-digit maintenance period in hours (Example: 0510 = 510 hours until maintenance
remainder). Unit saves period upon depression of fourth digit and returns to supervisor mode.
Note: Pressing “off” aborts procedure returning to supervisor mode.
6
Step 1: The unit will indicate entry into this procedure by repeating a display cycle that consists
of 2 amber flashes, 1 red flash, 1 amber flash and a pause. If the signal you are monitoring
is powered by the PSL+ output, you may turn the output on temporarily by pressing the “on”
key. Move the switch or whatever the VSI input is connected to into the position or setting it
will be at when you want the unit to consider the input to be active. For example, if you are
using a seat switch, then you should sit on the seat. When you are sure the input is in the
active state, press any numerical key. The unit will read the input and memorize what it “sees”
and then acknowledge with a long flash of the amber “accept” LED. You may also abort the
configuration procedure by pressing the “off” key if you notice that something isn’t right.
Step 2: After an acknowledge flash the display cycle will change to 3 amber flashes, 1 red flash,
1 amber flash and a pause. At that point you need to change the switch or setting to
the inactive position (in the previous example you would get off of the seat). When you
are sure the input is inactive, press a numerical key. This will prompt the unit to again
read the input. If the unit can detect a difference between the two states, another
acknowledge flash of the “accept” LED will be displayed and then the unit will return
to supervisor mode. If the unit can not detect a difference between the two settings,
then an error signal (short then long tone) will be sounded and the process will be
aborted (including the setting change you were making) and the unit will return to super
visor mode. If the output was turned on in step one; it will automatically go off upon
completion on this procedure.
Note: If you are having trouble getting the VSI input to configure properly, consider the following: The VSI
input is designed to detect three states: connected to ground, connected to the positive supply voltage
(B+) or open (not connected to anything). You may use any combination of those three. The VSI input is
not designed to detect voltage level changes within the supply range. Check the wiring to make sure the
input is being driven (or released) into a different one of the three states listed for the active and inac-
tive settings. Many vehicles draw power for such switches from the “key switch” line, so you may need
to turn the PSL+ on during configuration. If the problem still persists, please call for assistance.
Quick Steps – VSI (Vehicle Status Input)
1. Unit flashes 2 amber flashes, 1 red flash, 1 amber flash and a pause to indicate unit is ready to
receive vehicle input.
2. Apply vehicle active signal to blue wire. If this requires the PSL+ output to be on, press the “on” key.
3. Press any numerical key (0-9). Amber LED indicates acceptance of active input.
4. Unit then flashes 3 amber flashes, 1 red flash, 1 amber flash and a pause to indicate unit is ready
to receive vehicle inactive input.
5. Apply vehicle inactive signal to blue wire.
6. Press any numerical key (0-9). Amber LED indicates acceptance of inactive input. Unit returns to
supervisor access mode after inactive input is accepted. If the output was turned on, it will go back off.
Acceptable VSI Input States

Function 8 – Maintenance Reminder Frequency
The “8” key initiates a procedure to set how often the unit will sound the reminder sequence
(5 short beeps) if the maintenance cycle has expired and the output is on. Entry into this mode is
signified by a flash cycle consisting of 1 amber flash followed by 8 red ones. You may change this
setting whether or not the maintenance cycle function is enabled however; it has no effect until
it is. Settings are retained if the function is disabled and then enabled at a later date. You may
set the time between maintenance alerts in increments of 1 minute from 1 to 99. To set the time,
simply enter a two-digit numerical setting. Entries must be two digits (i.e. use 01 for 1, etc.) You
may manually abort the process by pressing the “off” key. After the second digit is entered, the
setting will be saved and acknowledged with a long flash of the amber “accept” LED and then the
unit will return to supervisor mode. The default setting is 15 minutes.
Quick Steps – Function 8
1. While in supervisor mode press 8. Unit will indicate Function 8 configuration mode active.
2. Enter two-digit number. Amber LED will indicate acceptance of selection and unit will return to
supervisor mode after second digit is entered. When maintenance time expires, unit will
output maintenance tone based on delay input in this function.
Function 9 – Display of Maintenance and Accumulated Time
The “9” key initiates a procedure which allows you to check the current maintenance cycle times
and total accumulated unit usage (in hours). Entry into this mode is signified by a flash cycle
consisting of 1 amber flash followed by 9 red ones. Upon entry into this mode you may choose
one of these three options:
1. Remaining time in current maintenance cycle
2. Elapsed active usage time since last MC reset
3. Total accumulated usage time of unit
Pressing any other key will generate an error and the function will be aborted returning you to
the supervisor menu. Upon making a legal selection 2 short beeps are sounded and then the
requested time is displayed by flashing the amber and red LEDs. Each digit is given by a number
of amber LED flashes followed by a red flash to indicate moving to the next digit. For example, a
time of 20,406 hours would be indicated by 2 amber + 1 red + (no amber) + 1 red + 4 amber +
1 red + (no amber) +1 red + 6 amber. (Zero is indicated by absence of amber flashes and will re-
sult in consecutive red LED flashes.) Upon completion of these flashes, there will be a long pause
and then the unit will return to the supervisor menu. Like Function 2, you may repeat Function 9
as many times as you like if you wish to double check the number of flashes. All time indications
are in hours and are rounded down to the last (next for #1) full hour. Selection options 1 or 2 will
produce an error beep if the maintenance cycle function is disabled. Option 1 will also produce
an error beep if the maintenance cycle is expired. In both cases, the function will be aborted
after the error has been indicated and the unit will return to the supervisor menu. The time that is
displayed for option 3 is the total accumulated time that the unit’s output has been on regardless
of any other function settings or the status of the VSI input. Time spent programming functions or
entering access codes is not counted.
Quick Steps – Function 9
1. Press 9. Unit will indicate Function 9 mode active.
2. Press 1. Unit will indicate remaining time in current maintenance cycle.
Or
Press 2. Unit will indicate usage time since last maintenance cycle reset.
Or
Press 3. Unit will display total accumulated usage time.
Note: Each digit is indicated by a number amber LED flashes followed by a red flash to indicate
moving to the next digit. For example, a time of 20,406 hours would be indicated by: 2 amber +
1 red + (no amber) + 1 red + 4 amber + 1 red + (no amber) + 1 red + 6 amber. Zero is indicated
by the absence of amber flashes and will result in consecutive red LED flashes.
Function 0 – Maintenance Cycle Reset
The “0” key resets the maintenance cycle time remaining to the last setting entered using the “7”
key function (or the default of 1000 hours if it has never been changed). You may do this if the
MC function is disabled; however it will have no effect until the function is enabled. If the MC time
had expired, the warning beeps will cease (until the new cycle expires). The amber “accept” LED
is flashed once to acknowledge the change was saved and then the unit returns to the supervisor
mode.
Quick Steps – Function 0
1. Press 0 in supervisor mode. Unit will clear time since last maintenance cycle reset and start new cycle.
On and Off Key Functions
On – The “on” key turns on the output and moves the unit to “on” mode. The supervisor becomes
the last user. The unit will not return to supervisor mode unless the output is turned off with the
“off” key and the procedure to enter supervisor mode is repeated (including entering the
supervisor code).
Off – The “off” key is used to exit supervisor mode and return to access code entry mode when you
have finished using the supervisor functions. The unit will also exit supervisor mode automatically
if no entries have been made for a period of 15 minutes.
As mentioned earlier, the Vehicle Status Input (VSI) must be configured before enabling the Auto
Shut Off (ASO) function or setting the Maintenance Cycle (MC) function for external control. Both
functions may use the VSI input at the same time, but the input will remain in the configuration
that was set when it was first activated. If both functions are deactivated at the same time, the
input will have to be configured again to use it. The VSI configuration procedure is automatically
triggered when needed and can not be initiated manually. If you change wiring and need to
reconfigure the input, disable ASO and set the MC control to internal then set them back to force
a new configuration. The VSI configuration procedure is a two step process. This procedure allows
the input to be flexible enough for use in a number of different types of applications and wiring
configurations.
