Spirax Sarco GS25039 (GS-X Series, Document Reference: TI-P794-01 / IM-P794-03)

ملاحظة هامة: 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.

1. تعريف الأسلاك الطرفية القياسية (General GS-X)

محطات الطاقة

ل / ن: AC power supply 100–240 V AC wide range

Protective earth PE: Instrument shield ground. Connect the shield of sensor cable only to this terminal at the controller side; do not ground both ends.

تحذير: Low voltage sensor loops (PT100, 4-20 مللي أمبير) must not be connected with 220 V AC and shall be isolated.

Sensor Input (IP1 Primary Input, IP2 Auxiliary Input)

PT100 (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 (ضغط / مستوى)

IP1+ / IP1-: الإشارة الحالية. The controller provides isolated 24 V DC transmitter supply (SU+, SU-) and can directly power Spirax Sarco pressure / أجهزة إرسال درجة الحرارة.

الحرارية: 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.

إخراج التحكم (OP1 / OP2 for main PID output, OP3 alarm relay)

لاحقة -10 in your model typically means isolated 4–20 mA analogue output (د1) for driving valve positioners such as SP7.

OP1+ / OP1-: 4–20 mA control output (معزول), connected to valve positioner

OP3 (كوم / لا / نورث كارولاينا): C-type alarm relay for high/low limit alarm and fault interlock

Other optional output types: تتابع (ر), bidirectional thyristor (ت), logic output (ل), determined by order code.

تواصل

RS485: أ / ب, مودبوس ار تي يو

Ethernet RJ45 port: Native high-speed Ethernet for iTools configuration, SCADA and IIoT upload. FC pre-configured units usually come with preset IP address.

Wiring Specification Notes

1. Separate sensor cables and power cables in different cable trays to avoid interference.
2. Shield cable rule: Shield grounded only at the controller end; leave the sensor end floating.
3. عزم الدوران الطرفي: 0.4 ن · م, conductor cross-section: 0.5–1.5 mm²
4. Power off before wiring. Verify I/O configuration and rear label before power-on. FC factory-configured units may differ from standard templates.
5. Troubleshooting Checklist for GS-X Steam PID Controller

Pre-operation: Back up parameters first. Use Spirax iTools software for backup to avoid configuration loss.

1. Steam-Specific Troubleshooting for GS-X
2. Desuperheating / heat exchange: PV fluctuation should first check blocked sampling pipe, condensate accumulation and sampling point in turbulent zone, not controller fault.
3. Valve position feedback: If valve position feedback is fitted, check 4–20 mA feedback loop; broken feedback will trigger valve position fault alarm.
4. 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.
5. Safe Maintenance Sequence
6. Isolate power, apply lockout-tagout
7. التفتيش البصري (محطات, الكابلات, التكثيف; high humidity in steam room easily causes terminal corrosion)
8. Continuity and insulation test
9. Inject simulated signal separately to distinguish sensor fault or controller body fault
10. Read alarm logs via iTools (alarm log is the most reliable fault source)
11. Check alarm code table first if alarm code exists
