Status Contacts

Relay contacts; closed indicates ∆F conditions OK

Relay contacts; closed indicates ∆V conditions OK

These are light duty contacts intended primarily for status interrogation by supervisory control They can be

used to light local lights with the following maximum restrictions: 1/2 A at 125 V dc resistive, 1 A 120 V ac,

250 V dc across open contacts

Minimum Frequency Difference

The guaranteed minimum frequency difference for operation is 0.0005 Hz; however, typical units consistently

operate with frequency differences of 0.0001 Hz.
