6.4.8 Test key C (open circuit)
"
Caution!
This test can be used to activate safety-specific measures in the plant (e.g. alarms)!
Pressing test key C disconnects the supply voltage.
If the power supply is disconnected, a supply unit such as Nivotester FTL325N from
Endress+Hauser reacts in such a way that the alarm relay outputs an error and appropriate responses
are triggered in any slave devices connected.
To perform the function test, proceed as follows:
1. Press test key C for the entire duration of the test.
The power supply from the supply unit is disconnected immediately.
2. All the LEDs go out. The safety functions (e.g. error message alarm) configured for the supply
unit are activated.
3. Release test key C again to end the function test.
