CAL CONTROLS Product Lines We Repair
Our engineers are trained on the full CAL CONTROLS product range. Below are the major product families we service.
3200 Series PID Controllers
Compact single-loop temperature and process controllers designed for industrial ovens, furnaces, and heat-treat applications. Common repairs include sensor input failures, relay contact oxidation, and display panel degradation in high-humidity environments.
9900 Series Multi-Loop Controllers
Advanced multi-loop control systems for pharmaceutical clean-rooms, sterilization chambers, and batch chemical processes. Frequent issues include proportional valve control failures, software glitches after power surges, and communication protocol breakdowns in networked setups.
3100 & 3300 Process Controllers
Integrated controllers for process variable measurement and alarm management in food, beverage, and dairy processing. Common faults include RTD/thermocouple signal conditioning failures, output card relay sticking, and memory corruption from thermal cycling.
Data Logger Modules
Compact data acquisition and logging modules for GMP compliance and production traceability in pharmaceutical and food industries. Repair needs include SD card interface failures, battery backup circuit degradation, and firmware corruption preventing data export.
Modular Control Panels
Rack-mount and panel-mount systems combining CAL CONTROLS controllers with auxiliary I/O modules and communication gateways. Common issues include card-edge connector corrosion, inter-module communication bus failures, and power supply voltage regulation problems.

Common CAL CONTROLS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CAL CONTROLS equipment arriving at our workshop.
- ✓RTD/Thermocouple Signal Input Failure — CAL CONTROLS analog input stages are sensitive to DC offset and noise on long sensor runs. In Indian textile mills and chemical plants, inadequate shielding and ground loops cause sensor signal dropout, false temperature readings, or complete input channel lockup.
- ✓Relay Contact Oxidation and Output Failure — CAL CONTROLS controllers use mechanical relays for on-off control of heaters, compressors, and solenoids. In humid manufacturing environments common across Indian coastal facilities, contact oxidation prevents relay closure, resulting in intermittent heating or process halts without alarm indication.
- ✓Display Panel Segment Faults and Readability Loss — Seven-segment LED and LCD displays on CAL CONTROLS 3200 and 3100 series fade or develop dead segments after 8-10 years in high-temperature plant rooms. Solder joint failures under the display connectors are a root cause in Indian facilities with poor thermal management.
- ✓Communication Protocol Timeout and Data Loss — CAL CONTROLS 9900 series controllers use proprietary serial and Ethernet protocols that fail when subjected to industrial electromagnetic interference or voltage spikes from nearby motor starters and power contactors. Indian manufacturing plants often lack adequate EMC filtering.
- ✓Power Supply Voltage Regulation Drift — Internal linear voltage regulators in CAL CONTROLS modular control panels drift out of tolerance due to capacitor aging and transformer core heating. This causes intermittent microprocessor resets, watchdog timer triggers, and loss of calibration data in pharmaceutical and food processing applications.
- ✓Firmware Corruption and Memory Address Errors — Extended thermal cycling and sudden power loss events corrupt CAL CONTROLS controller firmware, particularly in batch sterilization and autoclave systems. Memory CRC errors prevent the unit from booting or communicating across the industrial network.

Whether your equipment is 10 years old or brand new, Synchronics has the technical depth and spare parts inventory to restore it.
How do I know if my CAL CONTROLS controller needs repair?+
Common warning signs include erratic temperature readings, loss of sensor input, relay clicking but no output action, display segment failures, communication timeouts on networked controllers, and unexpected power resets. If your CAL CONTROLS unit shows fault codes or exhibits intermittent behavior, contact Synchronics immediately. We provide free diagnostic evaluation and turnaround timelines within 5-7 working days for most repairs.
Can Synchronics repair CAL CONTROLS controllers that lost calibration data?+
Absolutely. We recover original calibration parameters from controller memory using specialized EEPROM reading tools. If data is completely lost, Synchronics re-calibrates your CAL CONTROLS unit using precision reference thermocouples and RTD simulators, restoring accuracy to within ±0.2 degrees Celsius. We also back up your configuration to USB before returning equipment to prevent future data loss.
Do you supply CAL CONTROLS spare parts or replacement units?+
Synchronics stocks genuine CAL CONTROLS replacement parts including display modules, relay cards, input conditioning boards, power supplies, and communication interface modules. For controllers beyond economical repair, we source refurbished CAL CONTROLS units with full warranty. Contact our spare parts team in Vadodara to request quotes and delivery timelines.
