In switch mode, the selected relay can be switched on and off using the
key.
A blinking box signifies a relay in switch mode.
A dark box signifies an activated relay.
A light box signifies a deactivated relay.
WARNING!
Manually activated relays remain activated until they are manually switched off!
6.8 Alarm
You can set two threshold values:
Threshold value 1 is an upper threshold value. If it is exceeded, the alarm will be activated.
Threshold value 2 is a lower threshold value. If it is under-run, the alarm will be activated.
In both cases, the display will show the advisory “Threshold value exceeded“, and Relay
3 will switch. This can, in turn, activate an external sound warning such as a horn, or a
warning lamp.
NOTE!
The alarm function is only active if the controller is switched on, with the display
showing it is in AUTO mode. If the controller is switched to MANUAL, the alarm
alert is cancelled and the relay will switch OFF.
Alarm delay
Depending on the type of control processes being run, threshold values can also be excee-
ded during standard operations. To prevent that during any such brief overshoots an alarm
is set off, it is possible to set a delay time that must elapse before the alarm is activated.
In other words, the alarm will be activated only when the threshold value is either excee-
ded or under-run for a longer period of time than the delay time setting.
