Standstill monitoring
S1SW P
The S1SW P standstill monitoring relay is used to monitor standstill on DC and
three-phase motors.
Approvals
Unit features
- Standstill monitoring with and with-out rundown time
- Standstill threshold can be set Run-down monitoring time can be set
- Normally de-energised mode
- Measuring circuits are galvanically isolated
- No speed sensor is required
- Suitable for use with a frequency converter
Description
The standstill monitoring relay is en-closed in an S-99 slimline housing with
plug-in terminals.
Features:
Relay outputs:
Standstill: 1 auxiliary contact (C/O)
Fault: 1 auxiliary contact (C/O)
Operating modes:
– Standstill monitoring without rundown monitoring
– Standstill and rundown monitoring
- Potentiometer to adjust the switch on threshold and monitoring time
- Slide switch to double the measuring range
- LEDs for relay's switch status, fault status and supply voltage
- The S1SW P monitors the rundown on a three-phase asynchronous machine
with standstill detection. The regenerated voltage induced from the motor is
measured; standstill is signalled (relaycontact) if the value falls below a set threshold. A second relay signals a fault if the voltage does not fall below the set threshold within the set run-down monitoring time. The time measurement is started by closing a volt-free start contact (N/C contact on the motor contactor at Y3, Y4). The slide switches can be used to switch the measuring ranges.
