Troubleshooting
8.5.3 Test the relay card
In the TEST/MAINT menu, the relay function can be checked.
The relay function can be tested by manually switching the single relays on or off in the
FUNCTION TEST menu. Additionally, the current state of the relays can be requested in
the RELAY STATUS menu.
TEST/MAINT
OUTPUT SETUP
RELAY INT/EXT
FUNCTION TEST
RELAY 1-4
Sets the relay to on or off.
This setting has a higher priority than the current calculated state of the relay so the switching
behavior of each relay can be tested independently. The relay will return to the calculated state
upon exiting this menu.
ALL
Default: OFF
Sets Relay 1-4 to on or off.
SET OUTMODE
Default value: HOLD
Decides how other members react if they try to read the relay state while the relay card is in the
manual relay test. As the state of the relays in the test mode is not based on any calculations
other members reading this state probably have to be informed about this special situation.
There are three settings:
HOLD
Another reading member does not use the current read value but uses the last value before the
output current card was in the function test mode.
ACTIVE
Another reading member uses the current value even when the output current card is in the
function test mode.
TRANSFER The reading member uses an own substitute value for its own output value.
RELAY STATUS
Indicates the status for each relay and probe which is read from the relay card. There are three
different states possible:
SENSOR OK
The relay is working fine and the relay card is able to read the data from the probe to set the
relay state.
SENSOR MISSING
The relay cannot get data from the probe because the probe is not responding anymore. In this
case the relay has the state set in SET TRANSFER in sc1000 SETUP.
SENSOR FAIL
In this case the relay can communicate with the according probe, but this probe has an internal
failure and cannot provide reliable data. In this case the relay has the state set in sc1000
SETUP, SET TRANSFER.
