•
The OATS should be installed at an elevation
above the ground that will prevent accidental dam-
age or tampering.
•
Install field wiring from the OATS mounting loca-
tion to the control box for the control wiring. Do
not run field wires parallel to telephone or power
cables. If the sensor wires are located in an area
with strong sources of electromagnetic interfer-
ence (EMI), shielded cable or twisted pair should
be used. If using shielded cable, the shield wire
should be connected to the Com (–) terminal on
the control and not to earth ground.
•
Connect the two field wires from the OATS directly
to the control box “Com (-)” and “Os/V” (not polar
sensitive) terminals (Fig. 8).
Water Temperature Sensors (Supply & Return):
The Water Temperature
Sensor has a zinc sleeve
for fast response and a
wide operating range (Fig
5). Factory Pre-wired
Note:
Sensors are designed to mount on a pipe or in a
temperature immersion well.
•
The sensor can be strapped
directly to the pipe using the
cable tie provided. Insulation
should be placed around the
sensor to reduce the effect
of air currents on the sensor
measurement (Fig. 6).
