INSTALLATION AND POWER-UP
After all of the connections have been made, and the unit has been mounted securely, the
SST-4 is ready to be powered up. The following procedure describes the power up and
initial checkout.
With the ignition switch in the ON position, turn on the “Master” switch to power up the
SST-4. On initial power up the SST-4 will perform a self-diagnostic test to verify that all of
the functions are operating correctly. If a ashing “SP” is reported, the master switch was
turned on with the ignition switch in the off position. Turn on the iginition switch, and then
hold down the UP and DOWN buttons simultaneously for 5 seconds to clear the fault.
If no faults are detected, the SST-4 will go into “Run mode” and the hour meter readout will
be visible on the display (refer to Table 1).
If a fault is detected on power up, a code will be ashing on the display indicating in which
circuit the fault has occurred. For assistance in troubleshooting, please refer to the trouble
shooting section.
After all of the faults have been cleared and the SST-4 is operating in normal mode, apply
signals to test the proper function of the SST-4. Table 1 outlines the different display
codes and the operations which they indicate. Apply signals as available to ensure proper
operation of each function.When checking signals, verify the status of various signals on
the board by using the green display indicators, shown in and detailed in Table 2.

PROGRAMMING PROCEDURE
The following procedure describes how to view and change settings for SST-4 operation. These
procedures require the user to access the pushbuttons on the SST-4 circuit board: “MENU”, “UP”, and
“DOWN”.
Press the “MENU” button on the SST-4 board. The display will show the board’s current
operating conguration, starting with “A2”, that is, the system is set for dual plunger mode.
Press “MENU” again, and the next parameter is displayed. Repeat pressing “MENU” to
view all the settings, until the system returns to “A2”.
If changes are desired, press “MENU” until the target parameter is displayed. Use the “UP”
and “DOWN” keys to change the parameter to the desired value. The available choices are
those shown in Table 5.
To save changes, press and hold the “MENU” key for 5 seconds. The display ashes “SA”
to conrm that the conguration change has been saved.
If the conguration has been changed mistakenly, restore the SST-4 to its previous conguration by
holding the “MENU” and “DOWN” keys for three seconds. This will reload the last saved settings.
You can page through the congurations and see that it is as expected, then the settings must be saved,
by holding the “MENU” key for 5 seconds. The display will ash “SA” for conrmation of the save.
The SST-4 is preloaded with a factory default conguration. The default settings are displayed on
Table 3 with an asterisk (*). To recall these setting hold the “MENU” and “UP” keys down together
for 3 seconds. You can page through the congurations and see that it is as expected, then the settings
must be saved, by pressing and holding the “MENU” key for 5 seconds. The display will ash “SA” as
conrmation of the save. The table below shows a summary of the pushbutton controls.
It is important to note that changes are not saved automatically, but must be written to memory by
holding down the “MENU” key for 5 seconds. This includes any of the recall functions described
above. The values that were recalled are not made active until the user has saved them.

TROUBLESHOOTING
If a problem is encountered, the following procedure can be used to troubleshoot the system, and
identify and x some of the more common problems. If the problem is not easily identied, please
contact Wired Rite for assistance at 1-800-538-7483. Before beginning the troubleshooting, please
check these ve items:
System Lock-up. The processor on the SST-4 board can go into a locked-up situation if
the power is toggled on and off at a rapid rate. If this occurs the processor must be reset by
disconnecting the power to the board for several seconds and then reconnecting it.
Ground. The ground wire of the SST-4 must NOT be connected to the chassis, but routed
directly to the negative side of the battery.
On-board LED indicators. An additional troubleshooting resource is the on-board LED
indicators. These functions are described in Table 2. SST-4 Green LED indicators.
Diagnostic Display. If an error is detected by the SST-4, and parameter “L” is set to 1, the
display will ash to identify the problem circuit. Refer to Table 6 for locating the cause of
the fault.
Storing and clearing faults. If a fault occurs, the SST-4’s on board diagnostics will
record in which circuit the fault occurred and save the fault into memory. To clear all of
the recorded faults, press and hold the “UP” and “DOWN” buttons on the board for three
seconds or remove board power. This will erase the volatile memory and place the system
back in the “Run mode”
Troubleshooting Procedure
Begin with all inputs to the board OFF. Remove the enclosure lid if present to allow visual
inspection of the 4-character display and the relay status indicators.
Supply power to the SST-4 board. The 4-character displays should be active, for example
with two blinking decimal points. Check for board power on TB1 pin 3 (GND is available
on TB1 pin 1.) If there is no power, check the circuit breaker.
Turn the ignition ON. This should illuminate the relay indicators D5 (Starter Relay), D6
(Aux Relay), and D7 (Ignition Relay). If one or more indicators are not illuminated, then
that circuit may not be receiving power from the ignition splice. Check the associated
wiring path to ensure that the circuit is enabled. You may need to manually reset the
manual circuit breakers near each relay by pressing the yellow tab. NOTE: The Aux Relay
manual circuit breaker can be placed in two positions, depending on whether the system
incorporates a separate E-power battery. If there is a separate E-power battery, then the
circuit breaker should be connected between J5 and J6; otherwise it should be connected
between J6 and J7.
Turn ON the SST-4 MASTER switch. This is sometimes labeled “MACHINE” or “PTO” or
“AERIAL ENABLE” to indicate non-truck functions. This should activate the hour meter
on the 4-character display. If not, check that the signal from the SST-4 MASTER signal is
being applied to J1 Pin 3.
Apply START signal from the aerial switch. Indicator D2 should be illuminated. If not,
verify that the START signal is being applied to J1 Pin 5. Remove the START signal.
Apply THROTTLE signal from the aerial switch. Indicator D2 should be illuminated. If not
verify that the THROTTLE signal is being applied to J1 Pin 4. Remove the THROTTLE
signal.

Apply signal to activate the Start, Stop, and E-power functions as dened in the
programming settings. Verify that the 4-character display shows “St”, “SP”, and “EP” as
expected. If not, check programming settings (see Programming section). Set parameter
“L” to 1 and if the display is ashing “St”, “SP”, or “EP”, then there has been a fault in that
circuit. Check the manual circuit breakers and reset if necessary by pressing the yellow tab
on the circuit breaker.
Apply signal to activate the Throttle functions as dened in the programming settings.
Verify that the Throttle Relay Indicators D3 and D4 are activated. If not, check
programming settings (see Programming section).
Troubleshooting Quick Reference
The following table shows common problems and possible solutions when operating the SST-4. If the
problem is not easily identied, please contact Wired Rite for assistance at 1-800-538-7483.

APPENDIX II. CONNECTION TABLES
Ignition relay on SST-4 is “Normally Closed”. If power is not supplied to the board, the
ignition circuit will be closed and the ignition function will not be interrupted.
The SST-4 hour meter can be triggered either by the MASTER signal or the SPARE signal
on J1 Pin 1. This is user-programmable, as described in Section 5. PROGRAMMING.
T1 and T2 are identical, except T1 controls Relay 1 and T2 controls Relay2.

APPENDIX V. AUTO STOP ON LOSS OF PRESSURE MODE
This mode will force the SST-4 into STOP mode if loss of pressure is detected on a user-
installed circuit. This will then allow the user-specied stop mode settings to control. This
mode is especially useful in the situation where the vehicle stalls and the e-pump must be
used to control the aerial device. Setting the SST-4 and supplying a pressure switch to monitor
either the engine oil or the PTO hydraulic pressure will permit an automatic fail-over to the
e-pump without operator intervention.
Two inputs are used: the MASTER (J1 pin 3) input, usually connected to a switch controlled
by the operator to activate the SST-4, and the PRESSURE (J1 pin 1) input, which should be
connected to a pressure switch that senses either engine oil or hydraulic uid pressure. When
in this mode, and pressure is lost, the SST-4 will be forced into STOP mode after the delay
specied in parameter “o”.
Since there are many different types of pressure switches available in the market, parameter
“P” is used to describe how your particular switch functions.
When the system is in this mode, the hour meter counts only when both the MASTER input
and the PRESSURE input are true.
The pressure switch may be installed to measure either engine oil pressure or PTO hydraulic
uid pressure. If the switch is on the PTO, it is possible that the truck will be stopped
automatically if the operator-controlled master switch is turned on, but the operator does not
engage the PTO before the time out interval specied in parameter “o”. For this reason, it is
strongly suggested that the MASTER and PTO function be combined onto one switch.
Be certain to specify a delay interval in parameter “o” of sufcient duration to allow any
other timers to complete. This is especially true if you are utilizing parameter “F” (Glow Plug
Delay) as it is possible to set up a situation where the vehicle can never be restarted if “F” is
set to a period longer than “o”.
APPENDIX VI. TIMER NOTES
By using Menu “E - Throttle Mode Timer,” a delay can be created to use with the parameters of
Menu b marked with a †.
Parameter 5, Timed Operations: (start with T1 & T2 OFF)
Throttle trigger input > Menu “E” Delay > T1 ON
Next Throttle trigger input > Menu “E” Delay > T1 OFF, T2 ON
Next Throttle trigger input > Menu “E” Delay > T1 & T2 ON
Next Throttle trigger input > Menu “E” Delay > T1 & T2 OFF
REPEAT cycle
Parameter 9:
As soon as MASTER power is applied > Menu “E” Delay > T1 latches ON
Throttle trigger input > NO DELAY, then T2 momentary
REPEAT cycle without delay until STOP mode is entered, then the DELAY is activated again
Parameter A:
As soon as MASTER power is applied > Menu “E” Delay > T1 latches ON
Throttle trigger input > NO DELAY, then T2 Latches ON
Next Throttle trigger input > NO DELAY, then T2 Latches OFF
REPEAT cycle without delay until STOP mode is entered, then the DELAY is activated again
