Series Temperature Controller
Instruction Sheet
Thank you very much for choosing Delta DTE series temperature controller. Please read this instruction sheet carefully before
using your DTE to ensure proper operation. Keep this instruction sheet handy for quick reference.
Warning
DANGER! CAUTION! ELECTRIC SHOCK!
DTE is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from
operating the device (e.g. key or specific tools are required for opening the enclosure) in case danger and
damage on the device may occur.
1. Prevent dust or metallic debris from falling into the device and cause malfunctions. DO NOT
modify or uninstall the circuit
board of DTE without being permitted. DO NOT
use empty terminals.
2. Keep away from high-voltage and high-frequency environment during the 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.
3. The power has to be switched off when wiring or changing the temperature sensor.
4. When installing the circuit board of the accessory, please make sure the power of the main unit is switched off and insert
the accessory into the correct slot on the main unit.
5. Make sure to use compensation wire which matches the thermocouple or platinum resistance when extending or
connecting the thermocouple or platinum resistance.
6. Keep the wire as short as possible when wiring a sensor to the controller. Separate the power cable and load wire in order
to prevent interference and induced noise.
7. Make sure the power cables and signal device are installed correctly before switching on the power; otherwise serious
damage may occur.
8. DO NOT
touch the terminal or repair the device when the power is on; otherwise an electric shock may occur.
9. Please wait for 1 minute after the power is switched off to allow the capacitor to discharge and DO NOT
touch the internal
wiring within this period.
10. DO NOT
touch the internal terminal when DTE is either switched on or off in case you may damage the circuit.
11. Please place DTE with other heating objects (e.g. power supply) within proper distance while installing DTE.

Input
The standard DTE main unit is attached with 4 channels of inputs. You can purchase additional DTE20T or DTE20P to expand
the number of input channels. DTE supports maximum 8 channels of inputs which belong to group INA and group INB. Each
group possesses 4 input channels.
DTE series supports the following input sensors:

Communication address: Input sensor types at H10A0 ~ H10A7; input upper limits at H1010 ~ H1017; input lower limits at
H1018 ~ H101F.
Output
DTE supports maximum 16 channels of outputs, belonging to output groups OUT1, OUT2, SUB1 and SUB2, each group with 4
channels. See the explanations below for how input channels correspond to output groups.
Without group INB (4 channels of input): Every channel corresponds to 2 groups of output and 2 groups of alarms. OUT1 and
SUB1 are for control output, and OUT1 can be used for proportional output. OUT2 and SUB2 are fixed for alarm output.
With group INB (8 channels of input): Every channel is paired with 2 groups of outputs. OUT1 and OUT2 are used for control
output or proportional output of CH1 ~ CH8. SUB1 and SUB2 are used for control output or alarm output.
See Table 1 for the relations between input and output.

**When there are only 4 channels of inputs, OUT2 and SUB2 cannot be set up by the user but set up automatically as "alarm
output” by the controller.
Control Output:
DTE offers PID control, ON/OFF control, manual control and programmable PID control. Control output methods are set at
address H10B8 ~ H10BF (default = 0: PID), PID parameters at H1028 ~ H105F, ON/OFF parameters at H1058 ~ H106F, and
manual control parameters at H1070 ~ H107F.
Alarm Output:
DTE offers 12 alarm modes. The alarm modes are set up at address H10C0 ~ H10C7, upper limits at H1080 ~ H1087 and
lower limits at H1088 ~ H108F.

Synchronous Communication Protocol & Auto ID Setup
This function allows the auto setup of communication protocol in extension module DTC2000 and DTC2001 following the
communication protocol set in the DTE main unit. The station IDs of DTC decrease. See below for the steps.
1. Set the auto communication ID of DTE as “1” (communication address: H10F8).
2. Switch off DTE. Connect DTE with extension module DTC2000, DTC2001 and switch on DTE again.
3. Default communication protocol: 9,600bps, 7 bits, Even, 1 stop bit, communication address = 01.
