A Series Temperature Controller
Instruction Sheet
Thank you very much for purchasing DELTA A Series. Please read this instruction sheet
before using your A series to ensure proper operation and please keep this instruction
sheet handy for quick reference.
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 that this Delta A Series Temperature Controller is
protected throughout by DOUBLE INSULATION or REINFORCED INSULATION
(equivalent to Class II of IEC 536).
WARNING!
This controller is an open-type temperature controller. Make sure to evaluate any
dangerous application in which a serious human injury or serious property damage
may occur.
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).
2
Applicable wire: Solid/twisted wire of 2 mm , 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 "No 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.
• High radiation.
•
Vibration and shock.
• High voltage and high frequency
7. Must turn power 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 thermometer (RTD).
10. Please keep the wire as short as possible when wiring a platinum resistance
thermometer (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 supply 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
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.

Heating and Cooling Control
Temperature control is achieved either by heating or by cooling. The heating function
starts when the process temperature (PV) is going down, and the cooling function when
the temperature is getting high. It is impossible to operate both functions simultaneously
in this controller.
