1.4 Open/Short/Ground Fault Trip Values in Standby
Table 1.1 lists the earth fault resistance detection in standby for each applicable terminal on the FACP.
Value of the resistance in between any circuit terminal to Earth, which will cause the Ground Fault detection, depends on the ELR cho-
sen for inputs and output circuits. This resistance will vary from 9.9K down to 0 Ohm.
Table 1.2 lists the open/short trip values and restoral values in standby for the NAC circuits on the FACP.
NOTE: The PSE only supports 7AH or 18AH batteries in the cabinet. Other battery capacities up to 33AH will not fit in the cabinet due to
physical dimensions and require a separate battery cabinet.
Output Circuit Terminal Trip Resistance (in ohms)
NAC 1-5/7 + 9.9K or lower
NAC 1-5/7 - 9.2K or lower
ZNAC-PS 1-5/7 + 9.9K or lower
ZNAC-PS 1-5/7 - 9K or lower
Table 1.1 Earth Fault Trip Values
Circuit Fault Trip Resistance (in ohms) Restore Value
NAC 1-5/7 Short 1.6K or lower 1.7K or higher
NAC 1-5/7 Open 55K or higher 33K or lower
ZNAC-PS 1-5/7 Short 1.6K or lower 1.7K or higher
ZNAC-PS 1-5/7 Open 45K or higher 21K or lower
