Refer to Appendix H - Wiring Diagram and Appendix I - Sensor
Installation
Tools required:
• Small flat screwdriver for terminal connections
• Phillips and flat screwdrivers
• Cordless screwdriver
• Needle-nose pliers
• Wire cutters
• Scotch-Brite
• Two #8 x ½" self-tapping screws to mount DIN rail
1. Mount the controller in a rain-tight, protected location using
the supplied DIN Rail. To leave enough working space, the
suggested mounting area is 10 inches high and 5 inches wide.
The minimum depth is 3 inches. See Figures 1 and 2.
2. Connect the suction temperature sensor wires to terminals 31
and 32. The sensor is not polarized.

3. Connect the pressure transducer wires to terminals 33, 34,
1
and 35. Sporlan has used transducer cables with two wire
2
color combinations; see Table 1. Maximum torque on screw
3
terminals is 3.5 in-lbs.

4. Connect the optional room temperature sensor wires to termi-
5 nals 29 and 30. The sensor is not polarized.
5. Connect terminals 27 and 28 to a digital input. A short or a
6
closed contact from an external relay will close the valve for
7
pump down. See Section 4 - System Operation.
8
6. Connect the Sporlan EEV wires to terminals 5, 6, 7, and 8.
10
7. Connect power wires to terminals 1 and 2. Power require-
11
ments are 24 volts AC at 40 VA, Class II transformer.
12
8. Remove the protective clear film from the front of the Kelvin
14
II controller.

NOTE: Sensor leads may be extended to 100 ft. (30.5 m) with
15
18 awg wires and Scotchlok™ UR connectors for
15
long- term integrity.

WARNING: Route and secure cables away from hot surfaces,
20
high voltage lines, and moving components.
22
NOTE: The Sporlan Kelvin II refrigeration controller should
be installed only by a qualified professional. All other
system components (valves and sensors) should be
supplied by Sporlan to ensure compatibility and
proper operation. There are no user-serviceable com-
ponents inside the Kelvin II Controller. Opening the
case will void the warranty.
WARNING: Use caution when working around high voltage
components. Safety covers should be used for
personal safety on high voltage panels.
