AUMA ACVExC 01.2 Series User Manual

Setting range: 100 ... 150 % (in relation to the set tripping torque)
10.2. Motor protection monitoring (thermal monitoring)
In order to protect against overheating and impermissibly high temperatures at the
actuator, PTC thermistors or thermoswitches are embedded in the motor winding.
The thermoswitch is tripped 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.
●
Status indication: S0007Fault or S0011 Failure
-
Details: Thermal fault
The motor has to cool down before the operation can be resumed.
Depending on the parameter setting (motor protection behaviour), the fault signal is
either automatically reset or the fault signal has to be acknowledged manually.
Manual acknowledgement can be made:
●
in selector switch position Local control (LOCAL) via push button RESET.
●
in selector switch position Remote control (REMOTE) via a digital (I/O interface)
with the RESET command if a digital input is configured for RESET signal.
In addition, the actuator controls cyclically (once per day) check the motor protection
monitoring for its proper function. If this check fails, the controls generate the fault
indication: IE mot. prot. monitor
Motor protection behaviour
Required user level: AUMA (6).
Device configuration M0053
Actuator M0168
Motor prot. mode M0169
Default values:
Non-explosion-proof actuators = Auto
Explosion-proof actuators = Reset
Setting values:
Auto
Automatic reset after the motor has cooled down.
Not possible for explosion-proof version.
Reset
Manual reset.
Once the motor has cooled down, the fault has to be acknowledged (reset) manually
as described above.
If required the thermal overload relay has to be reset manually. To this end, remove
the cover on the back of actuator controls and operate the reset button on the thermal
overload relay.
10.3. Type of duty monitoring (motor starts and running time)
This function monitors the permissible type of duty (e.g. S2 - 15 min) of the actuator.
For this, controls monitor possible excess of
●
permissible motor starts (cycles) per hour
●
permissible running time (on-time) per hour
If any of these values has been exceeded, the actuator will however not be stopped,
but the following warning signals are issued.
●
Status indications: S0005 or S0008
