9) End of Line Monitoring (DC Units)
All DC units have a blocking diode fitted in their supply input
lines. An end of line monitoring diode or an end of line
monitoring resistor can be connected across the +ve and –ve
terminals in the flameproof chamber. If an end of line resistor
is used it must have a minimum resistance value of 3k3 ohms
and a minimum wattage of 0.5W or a minimum resistance
value of 500 ohms and a minimum wattage of 2W.
The resistor must be connected directly across the +ve and -
ve terminals as shown in the following drawing. The resistor
leads should be kept as short as possible. See D190-06-001
for details.

9.1. Custom DC Multi-Stage End Of Line Monitoring
An optional 12-way terminal module is available to enable up
to four alarm stages to be activated from three DC voltage
output channels. The three alarm stage activation inputs can
be independently monitored.
Refer to Schematic D190-06-001, Config. 6.
Specify Product option 'V' when ordering.
