5.5
Universal Sump Sensor
The Universal Sump Sensor (Figure 5-5) is used in an attached manway
riser, double-wall piping, or an attached collar riser. A sump sensor detects
the presence of any liquid in a piping sump. When enough liquid enters the
sump riser, it activates the sump sensor.
5.5.1 Installation
1. Place the Universal Sump Sensor into the sump.
2. Route the lead wiring into the junction box.
3. Adjust the length of the wiring until the sensor rests on the
sump floor (this dimension can be changed at your
discretion).
Secure the wiring into the box.
4. Connect the sensor to the VSmart Module by splicing the
sensor wires to the field wires. These wires,
in turn, pass through vapor seal-offs and enter the VSmart
Module.
5. Keep track of sensor-wiring identity to ensure proper wiring
at the VSmart Module. Follow all applicable codes.
6. Run separate wiring from each sensor to the chain leading
to the VSmart Module, if using the multi-drop connection
method; otherwise, run separate wire for each sensor.
Probe cables and sensor wiring can share the same conduit. Keep
track of sensor-wiring identity to ensure proper wiring at the VSmart
Module.
Maximum wiring length is the maximum length of cable to be used to
connect all sensors on an individual channel. This length includes the
run of the cable from the VSmart to each sensor board in the string.
