Locator Description
D Undervoltage Time Dial. Pushbutton switch that selects the desired overvoltage output
delay, either definite time (from 00.1 to 99.9 seconds) or, inverse time (characteristic
curves 01 through 99). A setting of 00 is instantaneous in either case.
E Power Indicator. This red LED lights when operating power is applied to the relay.
F Target Reset Switch. This switch is operated to reset the target indicators.
G Target Indicators. The electronically latched red target indicators illuminate when the
corresponding output relay energizes. To ensure proper operation of current-operated
targets, the current flowing through the trip circuit must be 200 mA or higher. Target
indicators are reset by operating the target reset switch (locator F).
H Output Test Pushbuttons. These pushbuttons allow manual actuation of the output relays.
Output relay actuation is achieved by inserting a nonconductive rod through the front
panel access holes.
I Undervoltage Pickup LED. A red LED that illuminates when undervoltage exceeds the
pickup setting.
J Undervoltage Pickup Adjustment. A multiturn potentiometer that sets the undervoltage
comparator threshold voltage. Continuously adjustable over the range indicated by the
style chart.
K Inhibit LED. A red LED that illuminates when the monitored generator voltage is under the
inhibit set point.
L Inhibit Pickup Adjustment. Multiturn potentiometer that sets the inhibit comparator
threshold so that whenever generator voltage falls below the set point, the (optional)
undervoltage measuring circuitry is inhibited from operation.
