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:
Input Sensor Type		Register Value	Range
	For DTE10P / DTE20P
Temperature measurement resistance (Cu50)		13	-50 ~ 150°C

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.

ƒWithout 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.

ƒWith 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.

	4 channels of input	8 channels of input
Output Group	INA (CH1 ~ CH4)	INA (CH1 ~ CH4)	INB (CH5 ~ CH8)
OUT1	Main control output or	Main control output or proportional	No corresponding output
	proportional output	output
OUT2	Alarm 1 output	No corresponding output	Main control output or proportional
			output
SUB1	Control output	Control output or alarm output	No corresponding output
SUB2	Alarm 2 output	No corresponding output	Control output or alarm output
		Table 1

Note: SUB1 and SUB2 do not support DTE20L and DTE20C. Please install the optional output modules you purchase into the correct slot.

Communication Address of Output & How to Set up Parameters:

See Table 2 for the communication addresses of output and Table 3 for the definition of the value in the address.

	CH1	CH2		CH3	CH4	CH5	CH6		CH7	CH8
OUT1, OUT2	H10A8	H10A9		H10AA	H10AB	H10AC	H10AD		H10AE	H10AF
SUB1, SUB2	H10B0	H10B1		H10B2	H10B3	H10B4	H10B5		H10B6	H10B7
				Table 2
	Value = 0			Value = 1		Value = 2			Value = 3
OUT1, OUT2**	Heating control			Cooling control		Proportional output			Disable output
SUB1, SUB2**	Heating control			Cooling control		Alarm output*			Disable output

Table 3

*When there are only 4 channels of inputs, SUB1 cannot be used for alarm output but heating/cooling control only.

**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.
