GROUND DETECTION ALARM RELAY (WITH LIGHTS)
5.9.1
Description
This alarm senses any ground, which may occur on the positive or negative battery terminal. One form C relay
contact for remote indication is available for positive and negative ground detection. The relay(s) energize(s)
during an alarm condition. The form C contact is rated to handle two amperes at 28 volts DC or 120 volts AC. A
local alarm light may be supplied to indicate a positive or negative ground.
5.9.2
Connections
The positive ground form C contact is terminated at TS4-7, 8, 9. The common (9) and normally open (8) contact
is closed during an alarm condition. The negative ground form C contact is terminated at TS4-10, 11, 12. The
common (12) and normally open (11) contact is closed during an alarm condition. Adjustment: None.
5.10
GROUND DETECTION VOLTMETER SWITCH
5.10.1
Description
A double-pole, double-throw momentary switch with a center off positive is used with the DC voltmeter. Placing
the switch in the POS or NEG test position connects that respective voltmeter polarity to ground.
5.10.2
Operation
If no ground exists, the voltmeter will read zero (0) volts when placed in either test position. If a ground does
exist, the voltmeter will read some voltage up to full bus voltage, depending on the amount of resistance to
ground. If the ground is solid (zero resistance), the voltmeter will read full bus voltage. As the resistance to
ground increases, the voltage read by the voltmeter will decrease.
5.11
GROUND DETECTION LIGHTS
5.11.1
Description
A light is connected from each power supply output ( positive and negative) to cabinet ground.
5.11.2
Operation
If no ground fault exists, the lights are dimly illuminated. If a ground fault does exist, one of the lights will
illuminate to greater brightness. The degree of brightness depends on the ground resistance.
