Operating principle

The function of standstill monitor with start-up override (S3 = I) or standstill monitor with rotation direction monitoring (S3 = II) can
be selected by means of DIP switches.
S3:
Function: Standstill monitor with
start-up override
Input I: Pulse input 1:
NAMUR
contacts (bounce-free)
Input II: Start-up override:
contact terminal 4 + 6: 20 seconds
contact terminal 5 + 6: 5 seconds
Output I: MIN/passive
Output II: MIN/active
Standstill monitor with start-up override (S3 = I)
If the frequency falls below the trip value set with the DIP switches S1 and S2, the standstill monitor with start-up override switches
the output I to passive and the output II to active. Input I is used to monitor the frequency of rising current edges. Signal
transmitters can be sensors in accordance with EN 60947-5-6 (NAMUR) or contacts. Input I is monitored for lead breakage/short-
circuiting. A start-up override can be initiated via input II. The duration of the start-up override can be selected between 5 and
20 seconds by means of a bridge (starting trigger) or an external trigger signal. During the start-up override time the outputs
assume the "no standstill" state. In this case there is no lead breakage/short-circuit monitoring at input II.
