Monitoring Relays
3UG Monitoring Relays for Electrical and Additional Measurements
■ Overview
The 3UG30 51 monitoring relay is used together with a sensor to
monitor drives for underspeeding.
■ Function
The underspeed monitoring relay operates according to the
principle of retriggerable OFF-delay. During the time (value) set
on the front panel, another pulse must arrive at input IN1 or IN2
to ensure that the output relay remains picked up. The
monitoring relay evaluates the rising edge of the signal, i.e.
a continuous signal is also recognized as a missing pulse. If the
retrigger pulse does not arrive, indicating a reduction in speed,
the output relay drops. In order to be able to start a drive, the
output relay remains picked up during the ON-delay time T, even
if the speed is still below the set value (motor starting override
time). The first pulse must come within this time.
The monitoring relay can be used for all functions where a
continuous pulse signal needs to be monitored (belt travel
monitoring, completeness monitoring, passing monitoring,
clock-time monitoring).
Speed monitoring without memory (NO MEMORY)
When the speed of the drive drops below the set value, the
output relay drops. It picks up again when the speed is greater
than the set value plus the fixed hysteresis.

Speed monitoring
Speed monitoring with memory (MEMORY)
When the output relay drops, this state remains stored even
when the speed reaches a permissible value again. The stored
state can be ended by a control signal at the reset terminal or by
interrupting the supply voltage for at least 200 ms.
