Motor protection (thermal monitoring)

Test procedure:
SARVEx16.2 Control unit: electronic (MWG)
Possible causes
Heating system (wiring diagram designation:
R5 H
) failure
Heating system defective
PTC tripping device defective
The "Motor protection tripped" signal (wiring diagram designation:
monitored:
"Motor protection tripped" = contact NC open (contact NO = closed)
When operating in combination with a suitable heating system within an ambient
temperature range exceeding the indicated temperature range of the sub-assembly,
the signal has to be integrated into the system circuit. The integrated heating system
within actuator controls (wiring diagram designation:
event of the "Motor protection tripped" signal (wiring diagram designation
Switch off the power supply of the heating system for temperatures significantly
exceeding 30 °C! Excessive device temperature signal due to failure of the heating
system might be the cause.
It is imperative to ensure the presence of the power supply of the optional heating
system for temperatures below 30 °C!
Automatic reset fuse as short-circuit protection for external 24 V DC supply for
customer (refer to wiring diagram)
In order to protect against overheating and impermissibly high surface temperatures
at the actuator, PTC thermistors are embedded in the motor winding. Motor protection
trips as soon as the max. permissible winding temperature has been reached.
The actuator is switched off and the following signals are given:
LED 3 (motor protection trippped) on the local controls is illuminated.
The status indications S0007 or S0011 Failure display a fault.
The fault Details is displayed when selecting Thermal fault.
The motor has to cool down before operation can be resumed.
Depending on the parameter setting (motor protection behaviour), the fault signal is
either automatically reset or the the fault signal has to be reset using RESET push
button with selector switch position Local operation (LOCAL).
Proof-test motor protection
The functionality of the motor protection must be verified at the latest when performing
the maintenance (refer to chapter <Servicing and maintenance>).
The test is performed by simulating the motor protection signal via actuator controls
local controls:
Required user level: Specialist (4) or higher.
