Series Valve Temperature Controller
Instruction Sheet
Thanks you very much for choosing Delta DTV series valve temperature controller. Please read this instruction sheet
before using your DTV to ensure proper operation. Keep this instruction 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.
DTV 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 malfunction. DO NOT modify or uninstall DTV 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 DTV
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.
DTV 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. DO NOT touch the internal
wiring within this period.
12.
DO use dry cloth and DONOT use acid or alkaline liquid to clean the device.

Note 1: The current input is built-in with a 249
Ω
precision resistor. See “How to Set up Current Input” section.
Note 2: The default setting is Pt100 input.
Note 3: To display the decimal point, you have to set up the parameter
(in the operation mode). The decimal point display is available for all
modes except for thermocouple B, R, and S type.
Note 4: The range for analog input is -999 ~ 9,999. Take 0 ~ 20mA for example, -999 refers to 0mA input and 9,999 refers to 20mA input. If we change
the range into 0 ~ 2,000, 0 will thus refer to 0mA input and 2,000 refers to 20mA input (1 display scale = 0.01mA).
Alarm Output
DTV offers 2 groups of alarm outputs and 17 modes for each group under the initial setting mode. When the PV
exceeds or falls below SV, the alarm output will be enabled. See the table below for the 17 alarm output modes.
