Dwyer 4V-3 - Manual

Series 4V/8V Valve Temperature Controller
Instruction Sheet
Thanks you very much for choosing Love 4V/8V series valve temperature controller. Please read this instruction sheet
before using your 4V/8V to ensure proper operation. Keep this instruction handy for quick reference.
1 Precaution
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.
Love 4V/8V 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
4V/8V 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. 4V/8V 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 DO NOT use acid or alkaline liquid to clean the device.

6 Types of Temperature Sensors & Temperature Range
Input Sensor Type Register Value Display Range
0 ~ 50mV analog input 17 -999 ~ 9,999
4 ~ 20mA analog input 16 -999 ~ 9,999
0 ~ 20mA analog input 15 -999 ~ 9,999
0V ~ 10V analog input 14 -999 ~ 9,999
0V ~ 5V analog input 13 -999 ~ 9,999
Platinum resistance (Pt100) 12 -200 ~ 600°C
Platinum resistance (JPt100) 11 -20 ~ 400°C
Thermocouple TXK type 10 -200 ~ 800°C
Thermocouple U type 9 -200 ~ 500°C
Thermocouple L type 8 -200 ~ 850°C
Thermocouple B type 7 100 ~ 1,800°C
Thermocouple S type 6 0 ~ 1,700°C
Thermocouple R type 5 0 ~ 1,700°C
Thermocouple N type 4 -200 ~ 1,300°C
Thermocouple E type 3 0 ~ 600°C
Thermocouple T type 2 -200 ~ 400°C

Note 1: 250Ω Precision Resistor must be used with current inputs.
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).
7 Alarm Output
