LOW VOLTAGE ALARM WITH ADJUSTABLE TIME DELAY
This alarm has an adjustable time delay form approximately 1 to 180 seconds. One set of form C contacts are
available for remote indication. An optional local alarm light can be provided.

Low Voltage Alarm Connection Diagram
5.7.2
Connections
The low voltage form C contacts are terminated at terminal strip TS4, points 4, 5, & 6.
5.7.3
Operation
Relay is energized under normal conditions. When low voltage condition occurs relay drops out after desired
time delay.
5.7.4
Adjustment Procedure
1.
Connect digital voltmeter, 20VDC scale to +TP and –TP where indicated.
2.
Energize power supply and adjust output voltage to desired alarm voltage.
3.
Adjust pot R6 clockwise to raise operating point, counterclockwise to lower operating point. Slowly
adjust R6 clockwise to cause voltmeter change abruptly from approximately 0V to 6.8V (low to
high); if voltmeter already reads high, adjust R6 counterclockwise to obtain low condition.
4.
Check setting by raising power supply voltage until relay resets then slowly decrease voltage until
voltmeter reads high. Note that trip is at desired voltage level. Readjust if necessary.
5.
Set pot R14 to desired time delay. Note: Scale on board is approximate time.
5.7.5
Specifications Same as High Voltage Alarm With Time Delay
