FD-1/FD-1N
MONITOR
Reset circuits (Reset 1, 2)
If an external start of the start-up delay or the reset for the latched output function
is to be possible, an external voltage of 24 V DC is to be supplied at the terminal 17
or 18.
For the monitor FD-1 the terminal 5 can be connected to terminal 17 or 18 via a NO
push-button/switch/plc relay output (not for the monitor FD-1 N).
The negative reference point of this voltage must be terminal 1 of the monitor.
A continuous 24 V signal continuously overrides the monitoring function, i.e. the
same state is signalled, as is the case during the start-up delay. Monitoring is started
when this voltage is interrupted and the set start-up delay has elapsed.
Load circuits transistor (Out 1, 2)
If you use the respective transistor outputs at terminals 16 and 24, these terminals
need a common external supply of 24 V DC at terminal 3. This voltage should not
be taken from the supply voltage of the pulse pick-up. The reference point of the
external power supply must be linked with terminal 1 of the monitor, otherwise
switching is not possible.
The device shall be supplied from an isolating source and protected by an overcur-
rent device such that the limited voltage circuit requirements in accordance with UL
508 are met.
Load circuits relay outputs (Out 1, 2 )
The monitor has 2 potential-free changeover contacts: terminals 13, 14, 15 (= out-
put 1) and terminals 19, 20, 21 (= output 2). If the unit often switches high exter-
nal inductive loads, you should protect the contacts against interference to meet the
EMC regulations and to avoid excessive wear and tear.
Load circuits fault outputs (FD-1 N)
The fault outputs (terminals 4 and 10) signal a wire fault between the monitor and
the pulse pick-up (wire break/short circuit). In case of a fault the corresponding
output is blocked.
