The GT, GE, LT, and LE comparison functions only differ in
the fact that GE and LE also switch when the value is equal
to the setpoint. To ensure that all analog value
comparators of AC010 devices are compatible with the
logic relays, the CL-LSR/CL-LST and the CL-LMR/CL-LMT
have five comparison modes.

Caution!
Analog signals are more sensitive to interference than
digital signals.Consequently, greater care must be taken
when laying and connecting the signal lines.
Set the switching hysteresis to a value so that interference
signals will not cause accidental switching. A value of 0.2
V (value 20 without gain) must be observed as a safety
value.
