2.2.3. Sensor Inputs
Sensors operate at low voltage and are isolated
from the supply. Make sure that sensor cables
remain isolated from all high voltage sources.
In particular, do not route the sensor cables
through the same electrical knockout as other
cables. Do not connect the shield from the
sensor cable to a terminal or a ground.
Extending a sensor:
Each sensor can be
extended up to 500 feet (150 meters).
To extend a sensor: Use a shielded cable of
outside diameter between 0.245 and 0.260
in (6.22 and 6.60 mm) (the cable dimensions
should not be under 18 AWG) to ensure the
cable entry is liquid tight.
Do not ground
the shielding.
It is preferable to solder the cable joint to
ensure a proper contact between the two
cables.
Do not run sensor cables next to other
power cables. When crossing over other
cables, cross at 90°.
Defective sensors:
An alarm is generated
when a defective sensor is detected. Defec-
tive sensors are identified in the
“Alarm Log”
menu. Refer to section 4.8 for further infor-
mation on the alarms.
2.2.4. 0-10V Output Connection
It is recommended to use a 18 to 22 AWG
wire to connect the devices to the 0-10V
outputs. This type of output can be used to
connect various devices such as lights.

LCD Potentiometer
(opt.)
LED display —
This screen shows the av-
erage room temperature and/or the static
pressure level.
Status LEDs —
The status pilot lights shows
the current status of the stages and outputs
of the controller. Refer to section 3.3 for
further information about these LEDs.
Arrow keys —
Use these buttons to select
an item displayed in the main screen and to
change the value of a parameter.
Enter/Modify button —
