Series Temperature Controller Instruction Sheet
Thank you very much for choosing Delta DTD series temperature controller. Please read this instruction sheet before using your DTD to ensure proper
operation. Keep this instruction sheet handy for quick reference.
Warning
DANGER! CAUTION! ELECTRIC SHOCK! When the power is on, DO NOT touch the AC terminals in case an electric shock may occur. Make sure
the power is disconnected when you check the input power.
DTD is an OPEN-TYPE device. If it will cause serious injury to workers or damage on other equipments when used in a dangerous environment,
please make sure it is installed in an automatic safety protection device.
1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, Max. width 7.2mm). Please be sure to tighten
them properly and make sure the wire is connected to the correct terminal.
2. Prevent dust or metallic debris from falling into the device and cause malfunctions. DO NOT
modify or uninstall DTD series without
being permitted. DO NOT
use empty terminals.
3. Keep away from high-voltage and high-frequency environment during installation in case of interference. Prevent using the device in
premises which contain:
(a) dust or corrosive gas; (b) high humidity and high radiation; (c) shock and vibration
4. The power has to be switched off when wiring or changing temperature sensor.
5. Make sure to use compensation wire which matches the thermocouple when extending or connecting the thermocouple wire.
6. Use wires with resistance when extending or connecting the platinum resistance sensor.
7. Keep the wire as short as possible when wiring a sensor to the temperature controller. Separate the power cable and load wire in
order to prevent interference and induced noise.
8. DTD is an open-type device. Make sure to install it in an enclosure which prevents dust and humidity in case of an electric shock.
9. Make sure the power cables and signal device are installed correctly before switching on the power; otherwise serious damage may
occur.
10. DO NOT
touch the terminals or repair the device when the power is on; otherwise an electric shock may occur
11. Please wait for one minute after the power is switched off to allow the capacitor to discharge and DO NOT
touch the internal wiring
within this period. Use dry cloth to clean the device. DO NOT
use acid or alkaline liquid to clean the device.
