What to do if no laser sent out from emitter on LNTECH Protection Device?
If the LNTECH Protection Device doesn't emit a laser when the press brakes upper mould is at the top dead center, it might be due to the press brakes being muted and the muting switch not disconnecting. Try stepping on the pedal to close the press brakes, which should allow the emitter to send out the laser normally. If this doesn't work, examine the muting signal.
Why does my LNTECH Protection Device stop working during press closing?
If the LNTECH Protection Device stops working when the press is closing, the safety output is disconnected, and you can't recover from this condition, it's likely that the workpiece is either too thick or made of wavy material, causing the E1 beam to be interrupted during closing. To resolve this, try setting a higher RPM.
What to do if press brakes returned trip, muting indicator is flashing on LNTECH Protection Device?
If the press brakes return during a trip and the muting indicator is flashing on your LNTECH Protection Device, it suggests that the muting signal is ineffective. This is often caused by a fault in the muting switch. Check the muting switch for issues.
What causes the fault indicator to flash twice per second on LNTECH Protection Device?
If the fault indicator on the LNTECH Protection Device is flashing twice per second, this indicates an abnormal muting signal or switch. This is likely due to a fault in the muting switch.
Why is the fault indicator flashing 5 times per second on my LNTECH Protection Device?
If the fault indicator on your LNTECH Protection Device is flashing five times per second, it indicates an EDM (External Device Monitoring) fault. This is probably due to an EDM disconnection.
What to do if slow speed indicator is off when press closing on LNTECH Protection Device?
If the slow speed indicator is off when pressing to close on the LNTECH Protection Device, it means the slow speed signal is ineffective. This is likely caused by a fault in the slow speed switch. Check the slow speed switch.
Why is the step pedal indicator off on my LNTECH Protection Device?
If the step pedal indicator is off on your LNTECH Protection Device, it indicates that the double pedal signal is ineffective. This is likely due to a wiring fault in the pedal switch.
