COMBINATION VOLTAGE/FREQUENCY SENSING
MODULE
Style No. 782OC99GO1
The card may be used as a replacement for older ver-
sions of the plug-in cards in existing equipment.
The card may be “programmed” to perform a voltage sens-
ing function, either undervoltage or overvoltage; and a fre-
quency sensing function, either underfrequency or
overfrequency.
Programming of the card is accomplished by positioning
jumpers on the positions labeled Jl through J12 on the
board itself. This allows easy field modification of the card
at the user’s discretion. Both the function and the pickup
and dropout values may be easily changed by following
the instructions provided.
Cards shipped from the factory are programmed to the
user’s original specification, or to the standard pickup and
dropout values as follow:
FUNCTION PICKUP DROPOUT
Undervoltage 90% 80%
Overvoltage 105% 115%
Underfrequency (60 Hz) 58 Hz 56 Hz
Overfrequency (60 Hz) 62 Hz 64 Hz
Underfrequency (50 Hz) 48 Hz 46 Hz
Overfrequency (50 Hz) 52 Hz 54 Hz
Programming the card
Reprogramming of the card may be accomplished by us-
ing the attached instructions with table 13, 14, 13A, 14A,
15 and 16.
It is recommended that you remove ALL jumpers from Jl
through J12. As supplied from the factory, there are
enough jumpers to program the card for any function and
value.
The card may be programmed for either UNDERVOLTAGE
or OVERVOLTAGE, and either UNDERFREQUENCY or
OVERFREQUENCY. Attempting to program the card for
two voltage sensing or two frequency functions ... WILL
CAUSE THE CARD TO MALFUNCTION AND POSSI-
BLY DAMAGE THE ELECTRONICS ON THE CARD!!
NOTE:
If the card is to be used as a replacement for older ver-
sions of the plug-in cards in existing equipment, please
check the Date Code that is stamped on the nameplate of
the Control Transformer Module (16OD997GO1 - G24).
* For Robonics with control transformer module’s date
code dated AFTER Sept. 1/92, follow Table 13 and 14
to program the voltage sensing function.
* For Robonics with control transformer module’s date
code dated BEFORE Sept. 1/92, follow Table 13A and
14A to program the voltage sensing function.
UNDERVOLTAGE PROGRAMMING
1. Place a jumper on J6.
2. Insure that there is NOT a jumper on J7.
3. Choose the desired pickup and dropout values from
TABLE 13 and place jumpers on the pins indicated.
4. For THREE PHASE sensing, place jumper on Jl (see
CAUTION below).

CAUTION:
If the card is to be used the THREE PHASE sensing, you
must insure that the sensing signals (Normal or Emer-
gency) are fed by a three phase transformer package. On
Westinghouse brand three phase unit sold by Cutler-Ham-
mer, the standard is three phase sensing on NORMAL,
and single phase sensing on EMERGENCY.
THREE PHASE SENSING ON EMERGENCY IS AVAIL-
ABLE ONLY AS A FACTORY INSTALLED OPTION. If in
doubt, contact the factory for assistance.
