Vertiv™ NetSure™ Control Unit (NCU) User Manual
NOTE!
The relay test can be exited at any time by setting the Relay Test to Disabled.
Manual Test
When placed in Relay Manual Test Mode, all relays on an IB2 board, EIB board, and NCU de-energize (since Fail Safe is enabled relay 1
on the 1st IB2 will be in alarm state, if wired for fail safe). Then you can individually change each relay’s state. The relay changes state
for the time period selected. At the end of the test, all relays are returned to their normal state (if no alarms are present). This is the
same procedure as “Manually Forcing Relays” on page 35 except you do not place the controller in Manual Mode.
