Channel Selection:
After positioning of the rotary switch, one or several channels in succession can
be selected for a function by pressing the respective key button (for more than
two seconds). After the two seconds have elapsed, all LEDs for the relevant
channel briefly light up.
Completion of Servicing:
If the key button is pressed once again (for more than two seconds)
or the maximum time preset for servicing is exceeded (software ConfigPro), this
function for the relevant channel will be terminated. With position 0 of the
switch on the controller module, the mainten-ance mode is completed and the
unit is back to normal operation. The yellow LED for ‘maintenance’ switches
off.
3.4.1. Forcing of the alarm relays into "out of alarm" position
Switch Position 1
Blinking of the LED for ‘fault’ indicates alarm suppression which prevents the
allocated relay from being triggered. The LEDs for channel information blink in
case of alarm, excess of measuring range or insufficient signal; the optional
LCD as well as the analog outputs continue to indicate the value measured. The
relays are not activated by alarms, faults, excess of measuring range or insuffi-
cient signals. When a relay operates in positive security, it remains in its initial
phase during the "test" period. The analog output signal is set to 2mA.
! ! Attention ! !
In case an alarm had been triggered and a relay had thus been activated
before alarm suppression was set up, the relay is de-activated.
Alarm suppression must not be used for calibration purposes.
