ment.
Use only in the safety circuit diagram.
f
Contact OM..ER: Closes in the event of an error.
Use in the safety and in standard circuit diagram. In a fault
scenario the contact TS..QS stays open.
g
Actual value output OM..QV: Indicates the current actual value
of the rotation frequency.
Indicated on the device or in easySoft-Safety.
h
Diagnostics output OM..DG: Provides information about the
states of the function block.
Evaluation only in the standard circuit diagram with the diag-
nostics function block DG.
Wiring of the function block
The relay uses different coils and contacts.
The coils OM..RE and OM..SA can be associated within the
safety circuit diagram. The following is an example of an
overspeed monitoring function block.
h
The speed input coils of the OM function block are
connected directly to device inputs IS1 and IS2 so that the
rotary encoder is always connected here and no function
block wiring is required.
j
Danger!
The device always regards two static High signals at
easySafetydevice inputs IS1 and IS2 as standstill, so that
the OM..QS contact is not switched off.
This behaviour applies also for two static Low signals if
these are applied to IS1/IS2 immediately after a change
into operating state RUN until the first Low-High edge is
detected.
h
easySafety enables the simultaneous operation of both
function blocks for zero speed and overspeed speed moni-
toring using the same sensors.
