I. Door body malfunction
\nThe sensor door cannot open automatically
\nTroubleshooting steps
\nCheck whether the induction probe is blocked by goods, dust, or the probe wiring is loose.
\nVerify whether the double-door interlock function is triggered (when one side door is not fully closed, the other side door cannot be unlocked);
\nConfirm whether the compressed air pressure is within the range of 0.4-0.6MPa (the pneumatic door needs sufficient air pressure to drive).
\nCheck whether the fuse in the control circuit has blown or whether the contactor is faulty.
\nSolution
\nClean the dust on the surface of the probe and re-fix the loose wiring.
\nMake sure that both door bodies are completely closed and the interlocking state is released.
\nAdjust the pressure of the air compressor to the standard range, inspect and repair the leakage points in the air pipe.
\nReplace the blown fuse, repair or replace the faulty contactor.
\n2. The door does not close tightly or gets stuck
\nTroubleshooting steps
\nCheck whether there are any foreign objects blocking the door body guide rails or if the guide rails are deformed.
\nCheck whether the sealing strip is damaged, fallen off, or the door hinge is loose.
\nTest whether the thrust of the pneumatic door cylinder is insufficient or the power of the electric door motor is abnormal.
\nSolution
\nClear foreign objects from the guide rails and correct deformed guide rails.
\nReplace the damaged sealing strip and tighten the hinge screws.
\nCheck the cylinder pressure and replace the aged cylinder. The electric door needs to have its motor or gear set inspected and repaired.
\nIi. Sprinkler System failure
\n1. The spray doesn’t start
\nTroubleshooting steps
\nConfirm whether the fan is operating normally (fan failure will cause no airflow in the spray).
\nCheck whether the nozzle is blocked by dust or debris.
\nCheck whether the parameters of the spray time controller have been tampered with or if there is a relay failure.
\nVerify whether the door closing signal is transmitted to the control system (the sprinkler does not start when the door is not fully closed).
\nSolution
\nInspect and repair the fan motor or circuit, and replace the faulty fan.
\nBlow the nozzle with compressed air to clear the blockage.
\nRecalibrate the spray time parameters (recommended to be 10-30 seconds) and replace the faulty relay.
\nAdjust the limit switch of the door body to ensure the normal transmission of the closing signal.
\n2. Uneven spray air output\/Small air volume
\nTroubleshooting steps
\nCheck whether the primary and high-efficiency filters are clogged (replace them when the pressure difference is greater than 200Pa).
\nCheck whether the nozzle Angle is offset or if some nozzles are clogged.
\nTest whether the fan speed is normal or if the belt is loose (belt-driven type).
\nSolution
\nClean or replace the clogged filter;
\nAdjust the nozzle Angle to the standard position and blow away the clogged nozzle.
\nTighten the fan belt and inspect the motor speed regulator.
\nIii. Control and Electrical Faults
\n1. The equipment cannot be powered on and started
\nTroubleshooting steps
\nCheck whether the main power switch has tripped and whether the power cord is loose or aged.
\nCheck if the emergency stop button has been pressed and not reset.
\nCheck whether the transformer and circuit breaker in the control box are faulty.
\nSolution
\nReset the trip switch, tighten the power cord and replace the aged circuit.
\nTurn the emergency stop button clockwise to the reset position.
\nRepair or replace faulty transformers and circuit breakers.
\n2. Interlock function failure (both doors can be opened simultaneously)
\nTroubleshooting steps
\nCheck whether the limit switch of the door body is damaged or the wiring is loose.
\nCheck whether the interlock relay in the control box is faulty.
\nVerify whether the program controller (PLC) outputs error signals.
\nSolution
\nReplace the damaged limit switch and reconnect the disconnected wiring.
\nReplace the faulty interlock relay;
\nReset the PLC program or contact the manufacturer for maintenance.
\nIv. Other common Faults
\n1. The operating noise is too loud
\nTroubleshooting steps
\nCheck whether the fixing bolts of the fan are loose or if there is too much dust accumulated on the impeller.
\nCheck whether the bearings of the fan are worn or lack oil.
\nVerify whether the door body is rubbing against the guide rail or whether the cylinder piston is worn.
\nSolution
\nTighten the bolts of the fan and clean the accumulated dust on the impeller.
\nAdd lithium-based grease and replace worn bearings;
\nAdjust the position of the door body, reduce the friction of the guide rails, and replace the aged cylinders.
\n2. The pressure difference in the clean area is normal
\nTroubleshooting steps
\nCheck whether the sealing strip of the door body is damaged, causing air leakage.
\nCheck whether the high-efficiency filter is clogged or damaged;
\nVerify whether the air volume of the fan meets the standard or if there is a leakage in the air duct.
\nSolution
\nReplace the damaged sealing strip;
\nReplace clogged or damaged high-efficiency filters;
\nInspect the fan and seal the leakage points in the air duct.
\nGeneral Precautions for troubleshooting
\nBefore all maintenance operations, power and gas must be cut off, and a “under Maintenance” sign must be hung. It is strictly prohibited to operate under power or voltage.
\nWhen replacing the filter, it should be operated on the clean area side to avoid contaminating the clean area.
\nIf the fault involves the PLC program or the core components of the motor, it is recommended to contact the professional personnel of the equipment manufacturer for maintenance.<\/p>","protected":false},"excerpt":{"rendered":"
