5.6 Electrical connec-
tion
The electrical connection of the flow
monitor is accomplished through the
connector plug or the cast on power
cable leading from the switch housing.
The switch contacts employed in these
devices are potential free and do not
require a power source. Switch con-
tacts and flow monitor have been opti-
mally harmonized. After replacement of
a switch contact, the switch point must
be readjusted.
