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
1.Always use recommended
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
(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
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.

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.
Ambient temperature | 0°C ~ +50°C |
Storage temperature | |
Operation altitude | Less than 2,000m |
Ambient humidity | 35% to 80% RH |
Setting up Parameters
Switching Modes: DTV is in the operation mode when the power is switched on, displaying PV and SV. Press for
more than 3 seconds to enter the initial setting mode. Press for less than 3 seconds in the operation mode to enter
the regulation mode. Press once in the regulation or initial setting mode to return to the operation mode.
Selecting parameters: In the operation, regulation or initial setting mode, press to select parameters for setup.
