  SW1.1: OFF (4-20mA input) SW1.2: ON (HART protocol enable) SW3.4: OFF (Channel 2 Thermocouple Type K)
- Inspect terminal torque: 0.6 Nm ±0.05 Nm (AWG 22-12)

‌Wiring Configuration‌

‌Channel 1 (Analog Input):‌

textCopy Code

TB1-1: +24V DC (Shielded Pair Red)

TB1-2: Signal+ (Twisted Pair White)

TB1-3: Signal- (Twisted Pair Blue)

TB1-4: Shield/Ground (Chassis GND Star Point)

‌Channel 2 (Analog Output):‌

textCopy Code

TB2-5: +Exc (To Actuator+)

TB2-6: -Exc (To Actuator-)

TB2-7: SENSE+ (Remote Feedback+)

TB2-8: SENSE- (Remote Feedback-)

‌Critical:‌ Maintain 50mm separation between input/output wiring bundles

‌Power-Up Sequence‌

Apply 24V DC power (Pins TB3-9/TB3-10)
Observe LED states:

‌LED‌ ‌Normal State‌ ‌Fault Indication‌

PWR (Green) Solid Off – Check L1/L2 fuses

CH1 (Yellow) Flashing 1Hz Solid – Input overrange

CH2 (Red) Off Flashing – Loop break
Allow 90s initialization (Watchdog timer reset required if >120s)

‌Calibration Procedure‌

‌Input Calibration (Channel 1):‌

textCopy Code

1. Apply 4mA reference source

   - Send MODBUS command: 0x06 0x03 0x00 0x5A 0x00 0x01

2. Apply 20mA reference source

   - Send MODBUS command: 0x06 0x03 0x00 0x5B 0x07 0xFF

3. Validate linearity:

   - Command: 0x03 0x03 0x00 0x41 0x00 0x02

   - Expect ±0.1% FS deviation

‌Output Calibration (Channel 2):‌

textCopy Code

1. Force 0% output:

   - Write 0x0000 to Holding Register 40002

   - Measure 4.00mA ±0.05mA

2. Force 100% output:

   - Write 0x2710 to Holding Register 40002

   - Measure 20.00mA ±0.08mA

‌Diagnostic Functions‌

‌MODBUS Registers:‌

‌Address‌	‌Function‌	‌Access‌	‌Data Format‌
30001	Ch1 Raw Value	RO	UINT16
30045	Ch2 Output Current	RO	IEEE754 Float
40012	HART Command	R/W	4x UINT16
