Spirax Sarco GS25039 (GS-X Series, Document Reference: TI-P794-01 / IM-P794-03)
หมายเหตุสำคัญ: GS25039-1-10-1810-FC is a factory pre-configured FC version. Terminal layout follows the general GS-X base board, while I/O modules (-1, -10) are order-selected options. Always refer to the terminal label printed on the back of the controller itself for on-site wiring. The general terminal definitions below shall not replace the nameplate of this unit.
- คำจำกัดความการเดินสายไฟเทอร์มินัลมาตรฐาน (General GS-X)
ขั้วไฟฟ้า
ล / เอ็น: AC power supply 100–240 V AC wide range
สายดินป้องกัน PE: Instrument shield ground. Connect the shield of sensor cable only to this terminal at the controller side; do not ground both ends.
คำเตือน: Low voltage sensor loops (พีที100, 4–20 มิลลิแอมป์) must not be connected with 220 V AC and shall be isolated.
Sensor Input (IP1 Primary Input, IP2 Auxiliary Input)
พีที100 (3-wire RTD, most common for temperature)
IP1+, IP1-, IP1-R: 3-wire RTD. Use shielded instrument cable for long runs and keep wire resistance balanced.
4–20 mA transmitters (ความดัน / ระดับ)
IP1+ / IP1-: สัญญาณปัจจุบัน. The controller provides isolated 24 V DC transmitter supply (SU+, SU-) and can directly power Spirax Sarco pressure / temperature transmitters.
เทอร์โมคัปเปิ้ล: IP1+, IP1-. Cold junction compensation parameters need to be set.
Digital DI (DIO1, DIO2)
Dry contact digital input (valve feedback, external interlock, remote start/stop), passive contact with internal pull-up.
เอาต์พุตควบคุม (OP1 / OP2 for main PID output, OP3 alarm relay)
คำต่อท้าย -10 in your model typically means isolated 4–20 mA analogue output (D1) for driving valve positioners such as SP7.
OP1+ / OP1-: 4–20 mA control output (โดดเดี่ยว), connected to valve positioner
OP3 (คอม / เลขที่ / เอ็นซี): C-type alarm relay for high/low limit alarm and fault interlock
Other optional output types: รีเลย์ (ร), bidirectional thyristor (ต), logic output (ล), determined by order code.
การสื่อสาร
อาร์เอส485: ก / บี, Modbus RTU
Ethernet RJ45 port: Native high-speed Ethernet for iTools configuration, SCADA and IIoT upload. FC pre-configured units usually come with preset IP address.
หมายเหตุข้อมูลจำเพาะสายไฟ
- Separate sensor cables and power cables in different cable trays to avoid interference.
- Shield cable rule: Shield grounded only at the controller end; leave the sensor end floating.
- แรงบิดในการขันขั้วต่อ: 0.4 น.ม, conductor cross-section: 0.5–1.5 mm²
- ปิดเครื่องก่อนเดินสายไฟ. Verify I/O configuration and rear label before power-on. FC factory-configured units may differ from standard templates.
- Troubleshooting Checklist for GS-X Steam PID Controller
Pre-operation: Back up parameters first. Use Spirax iTools software for backup to avoid configuration loss.
| อาการผิดปกติ | สาเหตุที่เป็นไปได้ | ขั้นตอนการแก้ไขปัญหา |
| ① No display when powered on | 1. Loss of supply, voltage below 90 VAC; 2. ฟิวส์ภายในขาด; 3. Loose power terminals; 4. Poor panel cable connection | Measure L-N AC voltage with multimeter; check terminals after power-off; inspect internal fuse; confirm it is not a 24 V DC model mistakenly wired to AC supply |
| ② “OPEN / SENSOR” sensor break alarm | Broken RTD, open 4–20 mA loop, ขั้วกลับกัน, no transmitter supply, excessive wire resistance | 1. Disconnect sensor and simulate signal at input terminal (PT100 resistance / 4 mA signal); 2. Check SU+ 24 วีเอาท์พุต; 3. Verify three-wire resistance balance for 3-wire PT100; 4. ตรวจสอบความเสียหายของสายเคเบิล |
| ③ Unstable reading, drifting or fluctuating PV | Incorrect shield grounding, parallel routing with power cable, unstable transmitter supply, aged sensor, oxidized terminals | Separate power and signal cables; correct single-point grounding; ขันขั้วต่อให้แน่น; replace sensor for comparison test |
| ④ PID no output, valve stays idle, PV/SV normal | Wrong output mode (คู่มือ / auto / locked), hardware-output mismatch, open output loop, faulty positioner, triggered DI interlock | Switch to manual mode and force output to check 4–20 mA; verify output type in configuration; measure current at OP terminals; check DI interlock status; test valve positioner independently |
| ⑤ Temperature / pressure hunting, การควบคุมที่ไม่เสถียร | Mismatched PID parameters, auto-tune not performed, large valve dead band, long steam loop lag, too small PV filter | Run Auto-tune first; increase integral time appropriately; check valve for sticking; increase PV filter; use Spirax Sarco native steam algorithm for steam systems |
| ⑥ OP3 alarm relay continuously energized / false alarm | Wrong alarm threshold, incorrect alarm logic (สูง / ต่ำ / ความผิดปกติของเซ็นเซอร์), DI interlock alarm, latched alarm not reset | Enter alarm menu and read alarm code; confirm alarm latch status; check PV range; clear alarm latch |
| ⑦ Communication failure (อาร์เอส485 / อีเทอร์เน็ต) | Mismatched IP / station address, inconsistent baud rate, สายเคเบิลเสียหาย, reversed A/B wiring, firewall / switch isolation, iTools password lock | Check communication parameters; fit termination resistor for RS485 bus; ping Ethernet; FC factory-configured units have OEM encryption and firmware flash is not allowed |
| ⑧ Panel keys no response | Keylock enabled, damaged panel, firmware exception | Unlock keypad; power cycle; read firmware status via iTools; do not flash generic firmware for FC custom firmware |
| ⑨ Parameters lost after reboot | Configuration not saved, failed internal backup battery, flash memory fault | Save after every modification and back up via iTools; return for repair if parameter loss recurs |
- Steam-Specific Troubleshooting for GS-X
- Desuperheating / heat exchange: PV fluctuation should first check blocked sampling pipe, condensate accumulation and sampling point in turbulent zone, not controller fault.
- Valve position feedback: If valve position feedback is fitted, check 4–20 mA feedback loop; broken feedback will trigger valve position fault alarm.
- FC = Factory Configured: Steam dedicated logic preloaded at factory. Do NOT reset to factory default, otherwise custom steam control logic will be lost and only Spirax Sarco can reissue configuration file.
- Safe Maintenance Sequence
- Isolate power, apply lockout-tagout
- การตรวจสายตา (ขั้ว, สายเคเบิล, การควบแน่น; high humidity in steam room easily causes terminal corrosion)
- Continuity and insulation test
- Inject simulated signal separately to distinguish sensor fault or controller body fault
- Read alarm logs via iTools (alarm log is the most reliable fault source)
- Check alarm code table first if alarm code exists
