COMBISCALE Product Lines We Repair
Our engineers are trained on the full COMBISCALE product range. Below are the major product families we service.
COMBISCALE Weight Transmitters & Indicators
Analog (4-20mA) and digital (RS-485, Profibus) weight display and transmission units. Common issues include zero-point drift, non-linearity after shock loads, connector corrosion in humid environments, and firmware communication failures affecting batch weighing accuracy.
COMBISCALE Dosing & Batch Control Systems
Integrated controllers for automated material dispensing in pharmaceutical mixing, chemical blending, and food production. Typical faults include setpoint drift, analog input card failure, loss of communication with remote load cells, and calibration memory corruption requiring emergency shutdown.
COMBISCALE Load Cell Interface Modules
Signal conditioning and amplification units bridging load cells to PLC/DCS systems. Repair addresses input-stage noise, filtering errors, excitation voltage regulation failure, isolation relay malfunction, and redundant sensor voting logic faults in safety-critical weighing applications.
COMBISCALE Networked Measurement Gateways
Multi-point weight data aggregation and Profibus/Ethernet gateway converters for plant-wide material tracking. Common failures include Ethernet PHY chip breakdown, Profibus termination resistance loss, data frame corruption, and timestamp synchronization loss affecting MES integration.

Common COMBISCALE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMBISCALE equipment arriving at our workshop.
- ✓Load cell output zero-point drift and nonlinearity — Repeated mechanical shock, thermal cycling in blast furnace or oven environments, moisture ingress causing bridge-circuit imbalance, or solder joint fatigue in the load cell amplifier circuit. COMBISCALE cells in Indian steel plants and foundries are particularly susceptible after seasonal humidity changes.
- ✓RS-485 Profibus communication timeout and no response from weight transmitter — Broken twisted-pair shield grounding, improper termination resistor installation (120-ohm matching error), EMI coupling from motor drives or VFD cables running parallel to weight signal wiring, or EEPROM corruption in the COMBISCALE transmitter's protocol stack.
- ✓4-20mA output stuck at 3.8mA or clamped full scale (20.2mA) — Precision current-output amplifier IC failure, DAC linearity error, or feedback resistor tolerance drift in COMBISCALE analog weight transmitters. Common in multi-year-old units where component aging reduces accuracy beyond ±0.5% specification.
- ✓Batch controller setpoint does not respond to keypad input or network commands — Front-panel switch matrix degradation from repetitive button presses, or corrupted parameter memory in the COMBISCALE DCS-700/900 microcontroller requiring factory reset. Loss of real-time clock battery also causes setpoint loss after power cycle.
- ✓Dosing overshoot causing batch weight deviation of +2 to +5 percent — Proportional integral (PI) loop gain misconfiguration or sensor response lag compensation setting drift in COMBISCALE COMBIDOSE system. Worn stepper motor drive, mechanical valve hysteresis, or loose valve linkage also causes sluggish flow response masking tuning errors.
- ✓Ethernet gateway drops connection to MES server intermittently every 4-8 hours — Ethernet PHY IC thermal stress or minor solder crack causing intermittent packet loss, ARP table overflow from plant network broadcast storms, or insufficient cable shielding grounding in COMBISCALE COMBI-GATE module. Firmware bug in network stack timeout handling also reported in units manufactured before 2015.

Frequently Asked Questions — COMBISCALE Repairs
Do you repair COMBISCALE equipment anywhere in India?+
Yes. Synchronics repairs the full COMBISCALE product range - load cells, weight transmitters, batch dosing controllers, and networked measurement gateways. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata and all other tier-1 and tier-2 cities. All repairs are performed at our 30,000 sq.ft. facility in Vadodara, Gujarat, with TAT typically 7-14 working days.
Can you recalibrate COMBISCALE load cells and transmitters to NIST or OIML standards?+
Yes. Synchronics provides NIST-traceable and OIML-compliant recalibration for all COMBISCALE load cells, weight transmitters, and analog output modules. Recalibration includes bridge resistance verification, temperature compensation testing across 0 to 40 degrees Celsius, and issuance of calibration certificates valid for regulatory audit and customer acceptance. We maintain precision 0.05% class weights and ±0.1% accuracy reference standards.
What is the typical repair cost and turnaround time for a COMBISCALE Profibus transmitter with communication failure?+
COMBISCALE Profibus transmitter repair typically costs INR 8,000 to 15,000 depending on fault severity and component replacement requirements. Turnaround time is 5-7 working days for standard diagnostics, firmware update, and communication validation testing. If component replacement or circuit board rework is needed, add 2-3 days. We provide advance quotation after power-on testing.
Do you supply spare parts for COMBISCALE equipment or only repair services?+
Synchronics provides comprehensive repair services including component-level repair, circuit board rework, and replacement of obsolete ICs and connectors. We stock common COMBISCALE spare parts such as amplifier modules, analog output cards, and Profibus interface modules.

Can Synchronics assist with Profibus termination configuration and wiring troubleshooting for COMBISCALE transmitters?+
Yes. Synchronics offers on-site or remote consultation for COMBISCALE Profibus network setup, including proper RS-485 twist-pair impedance matching, termination resistor verification, node address configuration, and baud-rate synchronization. Our engineers can perform Profibus protocol capture and analysis using industry-standard tools like SOFTING CombiScope to diagnose intermittent communication issues. We also provide documentation and training for plant maintenance teams on proper cabling practices for future installations.
How do I send my COMBISCALE unit for repair?+

What is the cost of repairing a COMBISCALE drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on COMBISCALE repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your COMBISCALE unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
