Operating mode

Overtemperature monitoring, 1 x 2 c/o contacts
With this configuration, settings via
operating function.
Open-circuit principle:
If the measured value is correct, the output relays remain de-
energized when control supply voltage is applied.
If the measured value exceeds the adjusted threshold value
the output relays energize. If the measured value drops again
below the adjusted threshold value
hysteresis, the output relays de-energize.
Closed-circuit principle:
The behavior is inverse to the one with open-circuit principle.
Overtemperature monitoring, 2 x 1 c/o contact
Open-circuit principle:
If the measured value is correct, the output relays remain de-
energized when control supply voltage is applied.
If the measured value exceeds the adjusted threshold value
output relay R2 (prewarning) energizes. If the measured value
exceeds the adjusted threshold value
switch-off) energizes.
If the measured value drops again below the adjusted threshold
t
value 1 minus the adjusted hysteresis, output relay R1 (final
switch-off) de-energizes. If the measured value drops below the
t
adjusted threshold value 2 minus the adjusted hysteresis, output
relay R2 (prewarning) de-energizes.
Closed-circuit principle:
The behavior is inverse to the one with open-circuit principle.

operating function.
Open-circuit principle:
If the measured value is correct, the output relays remain de-
energized when control supply voltage is applied.
If the measured value drops below the adjusted threshold value
t
2, the output relays energize. If the measured value exceeds
again the adjusted threshold value
hysteresis, the output relays de-energize.
