ANSI/IEEE C37.90-1978
UL file No. E58048
CSA file No. LR61158
Operation:
A.
The output relay will energize when all three
of the following conditions are met:
1. Voltage differential is below the preset
value.
2. Phase angle is below the preset value.
3. Frequency differential is below the preset
value.
B.
The relay is also provided with a "Double Dead
Bus" feature: When the voltage on either one
of the sensing inputs is below 15-25% of
nominal, (Dead Bus Condition), the output
relay will energize to permit paralleling.
When both sensing voltage are below 15-25%
of nominal, the output relay will not energize.

Options
A = two normal open contacts
B = two normally closed contacts
H = Contacts rated 3 amp at 125 VDC
P = Transient Protection
Transient Protection - All voltage relays will withstand
momentary voltage surges of twice the nominal rated input
voltage (standard).
PART NUMBER SELECTION
Notes:
1. Remove black cover screws to gain access to the adjustment potentiometers.
2. Clockwise rotation increases the trip differential setting.
3. Calibration terminals (11) (12) must be connected together to disable the phase angle
detector when setting the frequency difference trip point. Once it is set, the connection must
be removed.
