A.1 Mod 506: Capacitor Bank Switching
A.1.1 Description
The standard PQM software has been altered to allow the four output relays to be used for 
4 step capacitor bank switching.
A.1.2 Setpoints
The following messages have been added to the PQMII setpoint structure to 
accommodate this modif ication. The messages are located in setpoints page

•STEP 1(4) RELAY: The state of the output relay assigned in this message will be 
controlled by the 
STEP it is assigned to. Once a relay has been assigned to a particular 
step, it will not activate upon any other PQMII conditions (i.e. pulse output , alarm, etc.). 
If a particular relay has not been assigned to any 
STEP, it will function as per standard 
PQMII implementation.
•STEP 1(4) PICKUP: When the three-phase kvar value is positive and it becomes equal 
to or exceeds the value set in this setpoint the output relay assigned to the 
STEP will 
energize providing the conditions in all other setpoints are met .

•STEP 1(4) DROPOUT: When the three-phase kvar value becomes less than or equal to 
the value set in this setpoint the output relay assigned to the 
STEP will de-energize. 
Since over compensation is possible, the dropout value can be set to negative vars.
•STEP 1(4) PICKUP DELAY: The 
STEP will turn on after the delay set in this setpoint has 
elapsed assuming all other conditions have been met .
NoteThis delay setting will start counting down once the SYSTEM STABILIZATION TIME setting 
has elapsed.
STEP 1(4) DISABLE TIME: When 
STEP turns off, it is not allowed to turn back on until the 
time set in this setpoint has elapsed. This allows the capacitors to discharge before 
being re-energized again.
•SYSTEM STABILIZATION TIME: When any action is performed (turning 
STEPS on/off or 
low voltage is detected), the system must be allowed to stabilize for the time set in this 
setpoint before any further actions can be performed. This time is necessary to allow 
the system to stabilize without the capacitors trying to recharge
•LOW VOLTAGE LEVEL: When the system voltage (average three-phase voltage) 
becomes equal to or less than this setpoint , all 
STEPS are turned off. Upon recovery 
(three-phase voltage is greater than this setpoint) the time set in the 
SYSTEM 
STABILIZATION TIME
 setpoint must have elapsed before any actions will be performed. If 
this feature is not required, set it to “Off ”.
•LOW VOLTAGE DETECT DELAY: In some cases where noise or spikes are present on 
the line it may not be desirable to detect low voltage right away, therefore, this 
setpoint can be used to delay the detection until voltage is def initely low.
•STEP PRIORITY: The 
STEP PRIORITY setpoint determines the sequence the STEPS are 
allowed to turn on in a case where the condition may be satisf ied by more than one 
STEP. Therefore, the STEP with the highest priority will be energized f irst . If the STEP 
with highest priority is already energized, the 
STEP with second highest priority will be 
used, and so forth. The 
STEP priority is set from highest to lowest (left to right) when 
viewing this setpoint . For example, “1,2,3,4” signif ies that 
STEP 1 has the highest 
priority and 
STEP 4 has the lowest priority. Note that only one STEP is allowed to turn 
on or off at a time.
NoteEnervista PQMII setup software does not support any MODs. The settings and metering
values under this MOD can be accessed using the unit front panel or the Modbus analyzer
tools. 
A.1.3 Actual Values

•LOW VOLTAGE DETECT TIMER: This timer is loaded with the 
LOW VOLTAGE DETECT DELAY 
setpoint setting when low voltage is detected and will start to count down to 0.
NoteIf the power to the PQMII is removed all timers are cleared to 0.
A.1.4 Conditions Required to Energize a STEP
The following conditions are required to energize STEP 1. The same conditions apply to 
STEPS 2 through 4.
• Three-phase voltage is greater than the 
LOW VOLTAGE LEVEL setting.
• The system kvars are equal to or have exceeded the setting in 
STEP 1 PICKUP 
setpoint .
• The programmed 
SYSTEM STABILIZATION TIME has elapsed.
• The programmed 
STEP 1 PICKUP DELAY has elapsed.
•
STEP 1 has the highest priority as set in the STEP PRIORITY setpoint or all other STEPS 
do not meet all of the above conditions.
