C Series Temperature Controller
Instruction Sheet
Thank you very much for purchasing a Love Controls Series C Temperature Controller. Please read this instruction sheet before using
your controller to ensure proper operation and please keep this instruction sheet handy for quick reference.
1 Precaution
DANGER! Caution! Electric Shock!
1. Do not touch the AC terminals while the power is supplied to the controller to prevent an electric shock.
2. Make sure power is disconnected while checking the unit inside.
3. The symbol indicates this Controller is protected throughout by DOUBLE INSULATION or REINFORCED INSULATION
(equivalent to Class II of IEC 536).
WARNING!
Mount the controller in a location that will not be subject to excessive temperature, shock, or vibration. All models are designed for
mounting in an enclosed panel..
1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 7.0mm, hole diameter 3.2mm).
Screw size: M3 x 6.5 (With 6.8 x 6.8 square washer). Recommended tightening torque: 0.4 N.m (4kgf.cm). Applicable wire:
Solid/twisted wire of 2 mm2, 12AWG to 24AWG. Please be sure to tighten them properly.
2. Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning.
3. Never modify or disassemble the controller.
4. Do not connect anything to the “Not used” terminals.
5. Make sure all wires are connected to the correct polarity of terminals.
6. Do not install and/or use the controller in places subject to: Dust or corrosive gases and liquid, high humidity and high radiation,
vibration and shock, high voltage and high frequency
7. Power must be off when wiring and changing a temperature sensor.
8. Be sure to use compensating wires that match the thermocouple types when extending or connecting the thermocouple wires.
9. Please use wires with resistance when extending or connecting a platinum resistance sensor (RTD).
10. Please keep the wire as short as possible when wiring a platinum resistance sensor (RTD) to the controller and please route
power wires as far as possible from load wires to prevent interference and induced noise.
11. This controller is an open-type unit and must be placed in an enclosure away from high temperature, humidity, dripping water,
corrosive materials, airborne dust and electric shock or vibration.
12. Please make sure power cables and signals from instruments are all installed properly before energizing the controller, otherwise
serious damage may occur.
13. Please do not touch the terminals in the controller or try to repair the controller when power is applied to prevent an electric
shock.
14. Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any internal circuit
within this period.
15. Do not use acid or alkaline liquids for cleaning. Please use a soft, dry cloth to clean the controller.
16. This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch is required, install the protection
close to the instrument. Recommended fuse rating: Rated voltage 250 V, Rated current 1 A. Fuse type: Time-lag fuse
17. Note: This controller does not provide overcurrent protection. Use of this product requires that suitable overcurrent protection
device(s) must be added to ensure compliance with all relevant electrical standards and codes. (Rated 250 V, 15 Amps max). A
suitable disconnecting device should be provided near the controller in the end-use installation.

4 Operation
There are three modes of operation: operation, regulation and initial setting. When power is applied, the controller will default to the
operation mode. Press the key to switch to regulation mode. If the key is pressed for more than 3 seconds, the controller will
switch to the initial setting mode. Pressing the key while in the regulation mode or initial setting mode, forces the controller to return
to the operation mode. PV/SV : Sets the temperature set point and displays the temperature process value. Use the and keys to
set the temperature set point.
Setting method: While in any function mode, press the key to select the desired function and use the and keys to change
settings. Press key to save the changes. Menu items are listed below.
