OPERATION
The following settings and features are ommon to all ontrol modes:
Time Delay – Sets the operation time delay period. Using the Adjust swit h, sele t
the desired time delay, in se onds, from 3 to 600. This will delay both Open and
Close operations in both Manual and Automati operation mode by the time sele ted.
The Operation Pending light flashes before every Open or Close operation for the
period of time sele ted for the time delay. If in AUTOMATIC operation, the LCD
displays the operation type (Close or Open) and time until the operation will o ur.
If initiated by a MANUAL OPEN or MANUAL CLOSE ommand, the pending
operation an be aborted by swit hing to AUTO.
If initiated by a MANUAL OPEN ommand, and the Capa itor Bank is Closed, the
pending Open operation an be aborted by operating the MANUAL CLOSE swit h.
If initiated by a MANUAL CLOSE ommand, and the Capa itor Bank is Open, the
pending Close operation an be aborted by operating the MANUAL OPEN swit h.
Max Ops/Day – Sets the maximum allowable number of automati apa itor
bank lose operations per 24 hour period. This an be set from 2 to 24 operations
using the Adjust swit h. This setting overrides all other automati operation
settings. Manual operations do not ount against the limit set by MAX OPS/DAY.
Five Minute Close Inhibit – The ontrols use a built-in time delay to prevent the
line from losing into a harged Capa itor Bank. This “Close Inhibit” delay begins
after every Open operation and is a tive for 5 minutes. Neither Automati nor
Manual Close operations will take pla e while “Close Inhibit” is a tive.
Other Operational Features – If the ontrol loses power while the Capa itor
Bank Motorized Swit h is operating (either Open or Close Dire tion), an IMMEDIATE
operation o urs upon restoration of power, bypassing the OPERATION TIME DELAY.
This insures the Motorized Swit h finishes it’s travel.
If the ontrol loses power while CLOSE INHIBIT is a tive, an IMMEDIATE OPEN
operation o urs upon restoration of power, bypassing the OPERATION TIME DELAY.
If the user swit hes from AUTO to any of the rotary swit h Setup positions, and an
operation is pending, the operation is suspended.
If the user swit hes from any of the rotary swit h Setup positions to AUTO, and an
operation is pending, the operation is suspended.
Voltage Monitor (NoMAX®900 and 950) – When the front panel rotary swit h is
set to VOLT MONITOR, the display will show the sensed line voltage.
Temperature Monitor (NoMAX®900 only) – When the front panel rotary swit h
is set to TEMP MONITOR the display will show the measured ambient temperature.

LED INDICATORS
Auto – Indi ates the Control is in Automati mode and is using the operator
settings to ontrol the Capa itor Bank state.
Operation Pending – Flashes to warn the operator an operation is about to o ur.
In Automati mode, the LCD displays the type of operation about to o ur (i.e.
Close or Open), and the amount of time before it o urs. The OPERATION TIME
DELAY setting determines OPERATION PENDING period.
Close – When flashing, the CLOSE LED indi ates the Close Motor Relay
is energized. When solid, the CLOSE LED indi ates the Capa itor Bank is
onne ted to the line.
Open – When flashing, the OPEN LED indi ates the Open Motor Relay is
energized. When solid, the OPEN LED indi ates the Capa itor Bank is NOT
onne ted to the line.
Note: Both OPEN and CLOSE LEDs off indi ates the Control has re ently powered
on and the Line Voltage is within the Open and Close settings. There is not a
preferred Capa itor Bank state on the NoMAX®900; the operator settings and
Manual operations ontrol the Capa itor Bank state.
Manual Bank Control – The MANUAL OPEN and MANUAL CLOSE toggle swit h
is used to “Manually” Open or Close the Capa itor Bank. To manually CLOSE or
OPEN the apa itor bank:
Swit h the ontrol out of the AUTO mode, verify the red LED is off, and
sele t TIME DELAY. Using the ADJUST swit h, sele t the desired time delay,
in se onds, from 3 to 600.
Use the toggle swit h to OPEN or CLOSE the apa itor bank. The OPERATION
PENDING LED will flash for the duration of the sele ted time delay. The CLOSE or
OPEN LED will flash during the time the output is energized and will remain on.
Note 1: Pending manual operations an be an elled by turning the ontrol to AUTO.
Note 2: The apa itor bank annot be losed within less than 5 minutes from the
previous open operation to allow dis harge of the apa itor bank. See
Five Minute Close Inhibit se tion, page 12.
Note 3: Manual operations are ounted by the operations ounter ( lose operations
only), but manual operations do not ount against the preset daily limit set
by 24Hr Auto Ops. See Automati Operation se tion, page 14.
Manual Maintenance Operation – When the rotary swit h is in the AUTO posi-
tion, a Manual Open or Close is onsidered a maintenan e operation. The Manual
operation ompletes and the Control suspends its Automati testing for ten min-
utes. At the end of ten minutes, the Control reverts to Automati operation and will
automati ally Open or Close the apa itor bank based upon the Automati
Operation programmed settings. While in AUTO, the amount of time remaining
before Automati testing resumes is y led on the LCD.

WARNING: The Control will revert to Automati operation after 10 minutes
following a Manual Maintenan e Operation. The ontrol will then automati ally
Open or Close the apa itor bank based upon the Automati Operation
programmed settings.
AUTOMATIC
OPERATIONS
For the following operations,
please reference the
Overview Section (pg. 4)
to see if the operation
pertains to your control.
Automatic Voltage Operation –
Automati Voltage Control Mode
is a tive when the front panel
rotary swit h position is set to
AUTO, and the Control Mode is
set to VOLTAGE. The AUTO LED
will also light. When Automati
Voltage Control Mode is a tive,
the ontrol tests the Voltage
against the programmed Open
and Close settings. To adjust the
set points for automati voltage
operation, use the front panel rotary swit h to sele t the
parameter. Please refer to Figure 5.
1) OPEN VOLTS is the set point for opening the apa itor bank based upon
sensed line voltage. When the sensed line voltage rises above this set point for
one minute ontinuous, the ontrol will open the apa itor bank after the preset
time delay. Use the Adjust swit h to sele t the desired value. The minimum
value is the Close Volts setting plus 3 volts. The maximum value is 130 volts.
2) CLOSE VOLTS is the set point for losing the apa itor bank based upon
sensed line voltage. When the sensed line voltage drops below this set point for
one minute ontinuous, the ontrol will lose the apa itor bank after the preset
time delay. Use the Adjust swit h to sele t the desired value. The minimum
value is 105 volts. The maximum value is the Open Volts setting minus 3 volts.
The Line Voltage is tested at one-se ond intervals. The Line Voltage is averaged
over eight y les per interval.
The ontrol also in orporates an Adaptive Trip feature utilizing the Delta
Volt measurement. The Delta Volt measurement is the voltage ontribution
of the Capa itor Bank. If the next lose operation would ause the ontrol
voltage to be above the open voltage set point, the lose operation is not
performed until the voltage falls below the open voltage set point minus Delta

Volts. Similarly, if the next open operation would ause the ontrol voltage to
be below the lose voltage set point, the operation is not performed until the
voltage rises above the lose voltage set point plus Delta Volts. Upon power
on, Delta Volts is preset to 0.5 volts. At the first AUTOMATIC Close operation,
Delta Volts is set to the differen e measured just before the Bank Closes and
one-minute later. From that point on every four AUTOMATIC Close operations
are averaged. This average is used as the Delta Volts measurement.
Automatic Voltage Operation Control Priority
The OPEN VOLTS setting has priority over the CLOSE VOLTS setting.
Capacitor Bank Switching Coordination Feature – The OPERATION TIME
DELAY feature an be used to have the ontrol automati ally abort Voltage Open or
Close operations, thus allowing Capa itor Bank swit hing oordination.
If a Volt Open operation is pending, and the Line Voltage drops below the OPEN
VOLTS setting (minus 1 Volt) for 50% of the OPERATION TIME DELAY setting, the
Volt Open operation will be aborted.
Likewise, if a Volts Close operation is pending, and the Line Voltage in reases
above the CLOSE VOLTS setting ( plus 1 volt) for 50% of the OPERATION TIME
DELAY setting, the Volt Close operation will be aborted.
Example:
Two sites are ontrolled by a NoMAX®900 Control. The Cap Bank Voltage
ontribution is 2.2 Volts (i.e. Delta Volts is 2.2 volts).
Site 1’s CLOSE VOLTS setting is 118.0 and the OPERATION TIME DELAY setting
is 60 se onds.
Site 2’s CLOSE VOLTS setting is 118.0 and the OPERATION TIME DELAY setting
is 180 se onds.
The Line Voltage drops below 118.0 for more than 60 se onds, both Site 1 & 2
initiate pending Close operations (i.e. the Close Event ounters ex eed 60).
After another 60 se onds, Site 1’s Close Motor Relay energizes
(i.e. the OPERATION TIME DELAY for Site 1 is 60). Shortly thereafter, the
Line Voltage in reases to 120.2 volts (118.0 + 2.2 Volts Delta).
Site 2 is 60 se onds into its Operation Time Delay.
90 se onds later Site 2’s Close operation automati ally aborts
(i.e. the OPERATION TIME DELAY for Site 2 is 180) approximately
30 se onds before its Close Motor Relays would have energized.
Note: If a pending operation aborts, the Voltage ondition ounter
whi h initiated the operation, resets to zero.

While in Automati Voltage Control Mode, the ontrol will y le through several
different status messages. The messages in lude the Total Operations ounter, the
number of 24 hour Auto operations, the Line Voltage, the Present Time and either
the Delta Volts or any a tivated timer (i.e. the “Close Inhibit” timer, or the Manual
Open/Close maintenan e timer).
If the ontrol powers on into a high Line Voltage ondition (> 130.0 volts) an IMME-
DIATE OPEN operation o urs, bypassing the OPERATION TIME DELAY time.
Automatic Time Operation – Automati Time Control Mode is a tive when the
front panel rotary swit h position is set to AUTO and the Control Mode is set to
“Time”. The AUTO LED will also light. When Automati Time Control Mode is a tive,
the ontrol will open the apa itor bank when the ontrol lo k rea hes the “Open”
set point and the ontrol will lose the apa itor bank when the ontrol lo k rea hes
the “Close” set point, subje t to the weekend settings. To adjust the set points for
automati time operation, use the front panel rotary swit hes to sele t the
parameter. Please refer to Figure 5.
3) CLOSE TIME is the set point for losing the apa itor bank based upon the
ontrol lo k. To adjust this setting, the upper rotary swit h must be set to
TIME FUNCTIONS and the lower rotary swit h set to CLOSE TIME. Use the
Adjust swit h to sele t the desired time.
4) OPEN TIME is the set point for opening the apa itor bank based upon the
ontrol lo k. To adjust this setting, the upper rotary swit h must be set to
TIME FUNCTIONS and the lower rotary swit h set to OPEN TIME. Use the
Adjust swit h to sele t the desired time.
While in Automati Time Control Mode, the ontrol will y le through several
different status messages. The messages in lude the Total Operation ounter,
the number of 24 hour Auto operations and the present time.
Automatic Time Operation with Voltage Override Operation – Automati
Time with Voltage Override Control Mode is a tive when the front panel rotary
swit h is set to Auto and the Control Mode is set to “Time/Volt”. The Auto LED will
also light. When this mode is a tive, the ontrol will operate as des ribed for
Automati Time Operation as long as the sensed voltage is in the “non-Voltage
Control Range” (below the OPEN VOLT setting and above the CLOSE VOLT
setting). Automati Voltage Override will o ur when the sensed voltage rosses
either the OPEN VOLT or CLOSE VOLT setting with the following priority:
The OPEN VOLT setting has priority over the CLOSE VOLT setting, the CLOSE
TIME setting and the OPEN TIME setting.
The CLOSE VOLT setting has priority over the CLOSE TIME setting and the OPEN
TIME setting.

Automatic Temperature Operation – Automati Temperature Control Mode is
a tive for the NoMAX 900®when the Control Mode is set to “Temp. Only”
and the rotary swit h position is set to AUTO. The AUTO LED will also light.
When Automati Temperature Control Mode is a tive, the ontrol tests the
ambient temperature against the programmed OPEN TEMP and CLOSE
TEMP settings. To adjust the set points, use the front panel rotary swit h
to sele t the parameter. Please refer to Figure 5.
5) OPEN TEMP is the set point for opening the apa itor bank based upon
measured ambient temperature. Use the Adjust swit h to sele t the desired
value. The minimum value is 5 degrees. The maximum value is 125 degrees
(The Control prevents the OPEN TEMP setting from being loser than 5 degrees
to the CLOSE TEMP setting). The ontrol will issue an open ommand to the
apa itor bank based upon the Winter/Summer s hedule as follows:
Winter S hedule (defined by OPEN TEMP greater than CLOSE TEMP setting) –
When the ambient temperature rises above the OPEN TEMP setting for 5
minutes ontinuous, the apa itor bank will Open after the preset time delay.
Summer S hedule (defined by CLOSE TEMP greater than OPEN TEMP setting) –
When the ambient temperature drops below the OPEN TEMP setting for 5
minutes ontinuous, the apa itor bank will Open after the preset time delay.
6) CLOSE TEMP is the set point for losing the apa itor bank based upon measured
ambient temperature. Use the Adjust swit h to sele t the desired value. The
minimum value is 5 degrees. The maximum value is 125 degrees (The Control
prevents the CLOSE TEMP setting from being loser than 5 degrees to the
OPEN TEMP setting). The ontrol will issue a lose ommand to the apa itor
bank based upon the Winter/Summer s hedule as follows:
Winter S hedule (defined by OPEN TEMP greater than CLOSE TEMP setting) –
When the ambient temperature drops below the CLOSE TEMP setting for 5
minutes ontinuous, the apa itor bank will Close after the preset time delay.
Summer S hedule (defined by CLOSE TEMP greater than OPEN TEMP setting) –
When the ambient temperature rises above the CLOSE TEMP setting for 5
minutes ontinuous, the apa itor bank will Close after the preset time delay.
While in Automati Temperature Control Mode, the ontrol will y le through
several different status messages. The messages in lude the total operations
ounter, the number of 24 hour Auto operations, the present time and the
sensed temperature (Fahrenheit).
