Multiple ESD Sensor Probes to a Single Zone
Connect multiple ESD sensor probes to a single zone as follows:
1.
Ensure that the unit is powered OFF.
Connect the
leader cable
into the
sensor
input terminals
on the
interface board
. Do
not connect the green or white cores
(
2.
When connecting the leader cable to its
respective sensor input terminals, ensure
that the factory-issued
terminating resistor
is removed. Retain all resistors for future
fault finding/testing.
3.
Connect the series of ESD probes. Ensure
that:
a.
All EOL switches except the last
are set to the
‘OUT’ position
.
b.
The last EOL switch should be set to
the
‘IN’
).
