Settings of the standstill monitor (diagram)
MSI-SR-SM42OS-xx
Information on the outputs
The outputs Q1/Q2 can be used up to SIL 3.
The outputs Q3/Q4 can be used for controlling magnetically
operated interlocks up to SIL 1.
Setting of the speed to be monitored
The standstill frequency is set using the two rotary switches "x"
and "y".
Rotary switch
00 / 01 - 99
"ENTER" button: Activation of the function block and control circuit
functions
• Set the required operating mode, speed (at the rotary switches)
and the control circuit function (using external wiring at S1, S2,
I5).
• Then apply the operating voltage with the ENTER button
pressed; the ERR indicator flashes (max. 3 s).
• Release the ENTER button while the ERR indicator is flashing
(an error is detected if the ENTER button is pressed for longer
than 3 s).
The selected operating mode, speed and RESET function are
then saved and active.

ERR Error
X1/X2 are not safe semiconductor outputs.
X1 signals error states.
X2 signals the logic state of A and the RESET
request by I5.
RESET/BYPASS function I5/I6
The automatic (high)/manual (low) Reset function is defined
during the activation of the POU (see ENTER button).
• automatic RESET: A High signal at I5 (open) transmits the
comparator signal to the outputs.
• manual RESET: A High pulse at I5 transmits the enable of the
comparator to the outputs.
The transfer of the Reset signals can be influenced using
the Bypass function (ODER) at the input I6 of the
MSI-SR-SM42OS, If the input I6 is wired (HIGH), the outputs
Q1 and Q2 are permanently HIGH and Q3 and Q4 permanently
LOW. The generation of the bypass signal has to fulfill the same
safety requirements as the operating mode and the designated
safety function.
