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). 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 “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.

Operation

There are three modes of operation: operation, regulation and initial setting. When power is applied, controller gets into the operation mode. Press the key to switch to regulation mode. If the key is pressed for more than 3 seconds, 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. The next flow chart shows how to switch for settings and internal functions:

Note: AL-H and AL-L include AL1H, AL2H and AL1L, AL2L. With standby sequence: Meaning that the alarm output would be temporarily disabled until the PV value reaches the set value. Then, the alarm output will operate.
Current Transformer (CT) Function

The Current Transformer (CT) function is used with the alarm output. When using a current transformer (CT) with the controller, change the corresponding alarm output mode to mode 13 (alarm output set value is 13), then turn to operation mode and set the current lower-limit and current upper-limit. You can set current alarm range between 0.5A ~ 30A, display resolution is 0.1A and measure accuracy is +/- 0.5A.
