All the monitoring devices fitted must always be connected!
13.3.4.1 Monitoring of motor compart-
ment
The connection is made as described in the “Electrical connection” section.
13.3.4.2 Monitoring of terminal room/mo-
tor compartment
The connection is made as described in the “Electrical connection” section.
13.3.4.3 Terminal room, motor compart-
ment and sealing chamber monit-
oring
The connection is made as described in the “Electrical connection” section.
13.3.4.4 Monitoring of motor winding
DANGER
Risk of explosion due to overheating of the motor!
If the temperature limiter is connected incorrectly, there is a risk of explosion due to
overheating of the motor! Always connect the temperature limiter to a manual re-
activation lock. This means that a “release button” must be manually activated!
The motor is equipped with a temperature limit (1-circuit temperature monitoring). As
an option, the motor can be fitted with a temperature control and limit function (2-cir-
cuit temperature monitoring).
Depending on the version of the thermal motor monitoring, the following triggering
status must occur when the threshold value is reached:
ƒ
Temperature limiter (1 temperature circuit):
When the threshold is reached, deactivation
with reactivation lock
must take place!
ƒ
Temperature controller and limiter (2 temperature circuits):
When the threshold for the low temperature is reached, the motor can deactivate
with automatic reactivation. When the threshold for the high temperature is
reached, the motor must deactivate
with reactivation lock
!
CAUTION! Motor damage due to overheating! In the event of automatic reactiva-
tion, comply with the specifications for the maximum switching frequency and
switching break!
Connection of the thermal motor monitoring
ƒ
Connect the bimetallic strip via an evaluation relay. Relay “CM-MSS” is recommen-
ded for this. The threshold is preset.
