Relay contacts and inhibit input – Rockwell Automation 1606-XLS240UPSD Power Supply Reference Manual User Manual
Page 13

All parameters are specified at an input voltage of 24V, 10A output load, 25°C ambient and after a 5 minutes run-in time unless noted otherwise.
It is assumed that the input power source can deliver a sufficient output current.

13. Relay Contacts and Inhibit Input
The DC-UPS is equipped with relay contacts and signal inputs for remote monitoring and control of the unit.
Relay contacts:
Ready:
Contact is closed when battery is charged more than 85%, no wiring failure is recognized, input
voltage is sufficient and inhibit signal is inactive.
Buffering:
Contact is closed when unit is buffering.
Replace Battery:
Contact is closed when the unit is powered from the input and the battery quality test (SoH test)
reports a negative result.

Inhibit:
The inhibit input disables buffering. In normal mode, a static signal is
required. In buffer mode, a pulse with a minimum length of 250ms is
required to stop buffering. The inhibit is stored and can be reset by
cycling the input voltage. See also section 26.1 for application hints.
