DESCRIPTION OF THE ACTUATION
When the DI6 digital input is programmed to
the motor PTC input and the detector acts.
It acts as the levels:
P091 ≥ P672 = E33
P091 ≥ P673 = A33
It acts as the levels:
P092 ≥ P676 = E34
P092 ≥ P677 = A34
It acts as the levels:
P093 ≥ P680 = E35
P093 ≥ P681 = A35
It acts as the levels:
P094 ≥ P684 = E36
P094 ≥ P685 = A36
It acts as the levels:
P095 ≥ P688 = E37
P095 ≥ P689 = A37
The PT106 optional board was not detected
with P670 active.
When the conversion of the input current is
out of allowed range: 2,5V ±3%.
It detects the opening of the circuit of the
temperature channels, through the break of
some of the three wire of each sensor.
POSSIBLECAUSES
Excessive load on the shaft.
Loadcycletoohigh(largenumberofstartsand
stops per minute).
Ambient temperature too high.
Loosecontactorshort-circuit(resistance<100)in
the wiring from motor thermistor to X1 terminal of
the CCS6 board.
P268 is set to 7 without a thermistor installed at the
motor.
Stalled motor, locked rotor.
Motor overtemperature.
Motor overload.
Loadcycletoohigh(largenumberofstartsand
stops per hour).
Motor not develops the necessary torque for the
load.
Errorsandalarmslevelsadjustedarelowerthat
supported by the motor (motor class isolation).
PT106 optional board with problems.
If PT106 optional board will not being used, to
program P670=0.
Looseelectriccontactinthecurrenttransformer
cables or control board connection cables.
A thyristor or contactor in short-circuit.
Problems in the control board.
Motor temperature sensor with wire broken or
opened.
Temperaturechanneladjustedforerrororalarm
without sensor.
Connectors of the PT106 board not connected.
Comment:
Programming of the broken wire actuation as error
or alarm is in the P691.
