Digital inputs
Each monitor is provided with four electrically isolated digital inputs to enable and activate
the test values and to reset latched alarm outputs (see
A digital input signal with a voltage level between 13 V and 31 V is considered as "High"
signal. A "High" signal will activate the function of the corresponding input. A digital input
signal with a voltage level in the range 0 to +5 V is considered to be a "Low" signal. With a
"Low" signal at the input, the corresponding input will be in the initial state.
Terminals 3 and 16 are common reference points of the inputs.

The digital Reset Latch inputs of the three monitors are interconnected through the
backplane.
Reset Latch
Use this input to reset latched alarms and to reset the indicated rotational direction.
Before using this input for reset of the rotational direction, activate this function with the

does only react on an input pulse. This pulse must have a duration of at least 100 ms
before it is accepted from the monitor.
The Reset Latch inputs of the three monitors are interconnected through the backplane.
Therefore it is sufficient to connect Reset Latch to one of the three terminal blocks of the
system (see
Test Enable
Use this input to enable the test function. For the external activation of the configured test
value Test 1 or Test 2, it is necessary to enable the test value by this input.
