2 INSTALLATION
Select a location for the controller that is free
from corrosive gases and excessive dust. Avoid
direct sunlight, impact and radiant heat from elec-
tric ovens.
Prepare a panel cutout of 1.77 x 1.77" (45 x 45
mm) in a panel of 0.04 to 0.14" (1.0 to 3.5 mm)
thickness. (Note that the depth of the unit behind
the panel is 3.54".) Insert the unit into the panel
until it clicks into place. |

For a power supply of 110/120, connect to termi-
nals 1 and 5
For a power supply of 220/240, connect to termi-
nals 1 and 6 |
Thermocouple Input
Confirm the type of thermocouple and lead wire.
Connect the positive (+) lead (color-coded) to ter-
minal 2 and the negative ( - ) lead (red) to termi-
nal 3. Ensure that the total
resistance is 100 ohms maximum.
RTD Input |
Each of the three lead wires must have a resis-
tance of 2 ohms maximum (approx. 190 ft of 20
gauge Cu wire) and must all be of the same
resistance. Since the length of the lead wire will
have an effect on unit accuracy, use care in
selecting lead length.
Connect the red RTD lead to terminal 2 and the
black leads to terminals 3 and 4.

MANUAL RESET ADJUSTMENT (CN350,
CN360, CN370)
Use the screwdriver adjustment on the front of
the unit for manual reset (MR) when using pro-
portional control.
The controller is designed so that the proportion-
ing band is centered at the setpoint within 50%
“ON” and 50% “OFF” time (50% power).
Because the heater is never exactly sized for the
system, the process temperature will not stabilize
at the setpoint but at some other temperature
within the proportional band. This difference
between temperature and desired setpoint is
~ called “offset” or “droop”.

This offset is normal with single mode proportion-
al controllers and can be corrected by adjusting
the manual reset potentiometer. If there is stable
temperature lower than the set temperature, turn
the potentiometer clockwise (+ direction) and wait
until the process stabilizes. If there is a tempera-
ture higher than the set temperature, turn the
potentiometer counterclockwise (- direction) and
wait until the process stabilizes. Make these
adjustments in small increments. On processes
with a large thermal mass, the time between a
manual reset adjustment and stabilization at the
new temperature may be minutes.
CONVERTING THE CONTROLLERS TO
ON/OFF OPERATION (CN350, CN360, CN370)
The CN350, CN360 and CN370 Series
Controllers can be changed from Time Propor-
tional to ON/OFF operation by changing three
internal jumpers. To access these jumpers, the
unit must be removed from the case. To remove
the unit from the case, press the catch on the
bottom of the unit and slide the unit from the
case. The three jumpers (J1, J2 and J3) are on
the outside of the input board, which is on the
right side when facing the unit. Cut these
jumpers to convert to ON/OFF.

board.
7 HIGH LIMIT CONTROLLER (CN355/CN375)
These controllers have a normally energized
SPDT latching output relay which becomes de-
energized whenever the process variable (PV)
exceeds a selected setpoint value. To provide
reliable alarm action, the relay in this controller is
energized during normal controller operation.
When wiring to the relay, be sure to keep this in
mind. Use the reset pushbutton on the front
panel of the controller to reset the latching output
relay.
