ON switching point = limit value + ON hysteresis
OFF switching point = limit value – OFF hysteresis
ON switching point = limit value – ON hysteresis
OFF switching point = limit value + OFF hysteresis
An alarm is triggered, if the measured value falls
outside a defined range (Band).
Upper switching point = limit value + ON hysteresis
Lower switching point = limit value – OFF
hysteresis
An alarm causes the output to become active
(Relay energised, LED ON)
An alarm causes the output to become inactive
(Relay not energised, LED OFF)
In memory latch operation the status of the outputs
is stored in the event of a Power OFF condition
and then immediately restored at the next Power
ON.
In auto operation the status of the outputs is not
saved in the event of a Power OFF condition. At
the next Power ON the limit values are not
processed until after the expiration of the start
delay (PW.DELY).
