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.

|
|
| Sets the relay to on or off. | |
| RELAY | 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 | ||

|
|
| Default value: HOLD | |
| SET OUTMODE | 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 SYSTEM SETUP. | |||
|
|
| ||
|
|
| In this case the relay can communicate with the according probe, but this probe has an internal | |
| SENSOR FAIL | failure and cannot provide reliable data. In this case the relay has the state set in SYSTEM | ||
|
|
| SETUP, SET TRANSFER. | |
