ANDTEK AUTOMATION Equipment We Repair — By Category
ANDTEK AUTOMATION Product Lines We Repair
Our engineers are trained on the full ANDTEK AUTOMATION product range. Below are the major product families we service.
ANDTEK PLC Series
Compact programmable logic controllers featuring 16 to 64 digital I/O points, real-time processing, and Modbus TCP networking. Common faults include corrupt firmware, communication timeouts, and input/output module failures affecting production line synchronization.
ANDTEK HMI Touchscreen Range
7-inch to 15-inch industrial touchscreen terminals with IP65 front panel protection for factory floor environments. Typical issues include touch sensor unresponsiveness, backlight failure, Ethernet communication loss, and corrupted user interface databases.
ANDTEK Stepper Motor Driver Module
Microstepping drivers handling 2-amp to 5-amp output with step/direction interface for precision positioning. Repair-common faults include burnt FET transistors, encoder signal loss, overcurrent shutdown lockup, and power supply regulation failures.
ANDTEK Variable Frequency Drive (VFD)
Compact 3-phase AC motor drives rated 0.75 kW to 5.5 kW for pump, fan, and conveyor applications. Recurrent issues include capacitor bank degradation, IGBT module failure, thermal runaway in humid environments, and CAN-bus communication faults.
ANDTEK I/O Expansion Modules
16-channel analog input, 8-channel relay output, and mixed I/O modules for distributed automation architectures. Common repair scenarios include relay contact welding, 4-20mA analog circuit drift, digital optocoupler burnout, and terminal block corrosion.
ANDTEK Ethernet Communication Gateway
Industrial-grade protocol converter supporting Modbus TCP, Profibus, and EtherCAT for multi-device factory integration. Failure modes include RJ45 connector oxidation, Ethernet PHY chip failure, RAM corruption, and protocol stack lockup under high message load.

Common ANDTEK AUTOMATION Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ANDTEK AUTOMATION equipment arriving at our workshop.
- ✓ANDTEK PLC firmware corruption and boot loop — Power loss during firmware update, or faulty SD card slot contact causing sector errors. ANDTEK PLCs store bootloader and application code in serial flash memory vulnerable to incomplete write cycles, forcing restart loops and preventing communication with HMI or master controller.
- ✓ANDTEK HMI touchscreen complete blackout — Backlight inverter board failure or 12V power supply capacitor dry-out common in high-humidity Indian factory environments. ANDTEK HMI units operate 24/7 in conditions exceeding design temperature ratings, accelerating electrolytic capacitor failure and inverter circuit degradation.
- ✓ANDTEK stepper motor driver thermal shutdown during production — FET transistor junction temperature exceeding 125°C due to insufficient heatsink contact or overcurrent condition from shorted motor winding. Indian summer ambient temperatures combine with poor PCB thermal design in ANDTEK-SMD series, forcing thermal cutout after 30-60 minutes runtime.
- ✓ANDTEK VFD IGBT module short circuit and DC bus collapse — Moisture ingress combined with voltage overshoot from unfiltered AC supply transients triggers IGBT gate oxide breakdown in ANDTEK-VFD series drives. This manifests as 24V control supply voltage drop, loss of PWM output, and uncontrolled motor coast-down.
- ✓ANDTEK I/O relay contact welding and loss of discrete control — Inductive load switching surge (pump/compressor motor start) exceeds relay arc suppression capacity in ANDTEK-RO8 modules. Contacts weld closed under arcing conditions, preventing relay de-energization and locking critical machinery controls in unsafe state.
- ✓ANDTEK Ethernet gateway CAN-bus protocol timeout and device unreachable — Ethernet PHY IC (88E1512 variant) firmware mismatch or RJ45 jack connector pin oxidation breaks link establishment. ANDTEK-GWCOM gateway cannot negotiate speed/duplex with network switch, causing intermittent frame loss and CAN gateway timeout errors.
