GUARDALL Product Lines We Repair
Our engineers are trained on the full GUARDALL product range. Below are the major product families we service.
Guardall Electronic Interlock Systems
Safety-rated door interlocking systems integrating solenoid actuators with electronic control modules. Common failures include solenoid coil burnout due to continuous energisation, relay contact welding in safety circuits, and sensor misalignment causing false unlock signals.
Guardall Solenoid-Operated Latch Assemblies
Heavy-duty electromechanical latching mechanisms for pressure vessel doors, autoclave chambers, and hazardous area enclosures. Typical issues include armature stick-slip, plunger corrosion in chemical environments, and loss of holding force due to spring fatigue.
Guardall Safety Sensor Modules
Integrated proximity and position sensors for interlock feedback and door status monitoring. Repair needs include sensor cleaning for correct proximity detection, cable shielding issues causing intermittent signals, and calibration drift in harsh industrial environments.
Guardall Access Control & Monitoring Panels
Electronic control and display modules managing multi-point locking sequences and audit logging. Common faults include capacitor degradation in power supply circuits, loss of EEPROM configuration data, and relay chatter in safety-critical switching operations.
Guardall Emergency Release & Override Systems
Manual and powered override mechanisms for safety-interlocked access points and emergency egress. Typical failures include mechanical detent wear, solenoid hold-in coil burnout, and loss of manual release spring tension over time.

Common GUARDALL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GUARDALL equipment arriving at our workshop.
- ✓Solenoid coil burnout and loss of latch holding force — Guardall solenoids fail due to continuous de-energisation duty cycle, thermal overload in sealed enclosures, or incorrect coil winding specification. Held-energised circuits without proper thermal management cause insulation breakdown and open-circuit coil failure.
- ✓Interlock sensor misalignment and false unlock signals — Guardall door interlocks use precision mechanical actuators and proximity sensors. Misalignment from door sagging, vibration-induced drift, or incorrect sensor calibration causes intermittent unlock signals, triggering false alarms or unexpected door opening.
- ✓Relay contact welding and stuck safety circuit outputs — Guardall safety-rated control modules use relays for critical switching. Welded contacts result from inrush current spikes, contaminated contact surfaces, or undersized relay ratings for solenoid load. Stuck outputs prevent normal interlock release cycles.
- ✓Capacitor degradation and power supply instability — Guardall electronic control panels use electrolytic capacitors in power supplies. Age, high ambient temperature in industrial enclosures, and ripple current overload cause capacitor ESR increase, leading to low voltage output, intermittent resets, and system lockout.
- ✓EEPROM configuration loss and access control panel amnesia — Guardall MonitorPanel and ControlHub modules store safety settings, audit logs, and unlock sequences in EEPROM. Corruption occurs from power surges, flash memory wear-out, or corrupted firmware updates, causing the panel to lose programmed interlock logic.
- ✓Loss of manual emergency release function — Guardall EmergencyRelease and ManualOverride mechanisms use spring-loaded mechanical detents and manual levers. Springs fatigue, detents wear, or solenoid hold-in coils fail, preventing personnel from manually releasing the lock during power loss or emergency situations.

Frequently Asked Questions — GUARDALL Repairs
Do you repair Guardall equipment across India, and do you handle safety certification?+
Yes. Synchronics repairs the full Guardall product range — interlocks, solenoid latches, sensors, and control panels — with PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all other cities. Our repairs maintain safety integrity; we provide full traceability documentation and testing certificates required for compliance audits and regulatory inspections. All work is completed in our Vadodara facility with certified test equipment.
What is the typical turnaround time for Guardall interlock repair, and can you provide temporary replacement units?+
Standard turnaround is 5-7 working days for diagnosis, repair, and safety testing. For critical applications, Synchronics can arrange temporary loan interlock units (with compatible specifications) to minimise production downtime. We also prioritise emergency repairs for safety-critical equipment; contact our team immediately for rush service options.
Our Guardall solenoid keeps burning out every 6-12 months. What causes this and how do you prevent it?+
Solenoid burnout in Guardall systems typically results from continuous energisation, undersized coil ratings, poor thermal management in sealed enclosures, or excessive ambient temperature. Synchronics identifies the root cause through circuit analysis and thermal imaging, then implements solutions — coil upsizing, thermal management upgrades (heatsinks or cooling), reduced duty cycle programming, or control circuit modification. We warranty repairs against repeat failure within 12 months.
Can Guardall safety interlocks be retrofitted to older door locking installations?+
In most cases, yes. Synchronics engineers assess your existing door assembly, mechanical clearances, and safety requirements to specify compatible Guardall interlock models (EI-2000, EI-3000, or custom solenoid configurations). We provide installation design support, handle mechanical and electrical integration, and conduct full safety validation testing to ensure the retrofitted system meets current industrial safety standards.
How do I know if my Guardall interlock has failed, or if the problem is in the control wiring?+
Common signs include: false unlock signals (interlock releases unexpectedly), no solenoid response (stuck locked), audible clicking (relay chatter), or slow latch engagement. To diagnose, we perform non-destructive testing — measure solenoid coil resistance, check sensor output signals, test relay switching, and inspect control circuit voltages. If the interlock itself is faulty, we repair or replace it; if wiring or external circuits are at fault, we advise on corrections. Contact us with fault symptoms and we can often diagnose over the phone.
How do I send my GUARDALL unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GUARDALL 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 GUARDALL 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 GUARDALL 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.
