panel-mount system, it is best to make all connections at the time of physical
installation.
Wall mounted chlorine monitors are shipped with the power cord already
connected. If no outputs or alarms are to be used, all that is necessary is to
plug the probe cable into the receptacle at the bottom of the enclosure and
plug the power cord into a standard wall receptacle.
ac power can also be routed directly to the monitor in panel-mount
installations by connecting Line (L), Neutral (N), and ground (GND)
connections as shown in the
Warning: Remove ac power to the instrument before proceeding.
In order to access the terminal strip to make relay and output connections,
remove the four screws from the front panel and remove the front panel. Next,
remove the two screws on the right side of the display board (the display
board is hinged) and swing the display board out of the way. Make all
necessary connections in accordance with the
enclosure.
Connection mnemonics are V1 and V2 (voltage 1 and 2), I1 and I2 (current 1
and 2), AL1 (alarm 1), AL2 (alarm 2), and CHK (check relay).
The two basic methods of connecting the probe are:
•
Directly connecting the probe connector to monitor-connector P1 and,
•
Connecting the probe connector to an intervening junction box.
The second method allows greater distance between the monitor and the
probe (up to 200 ft. between monitor and probe connector). It also is useful in
