A specific reset of the system is required (the system will carry out a reset procedure by moving the car to the highest floor).
The cabin has reached a final limit switch, or the speed limiter and/or the parachute has intervened. In all cases, point #3 of the safety chain remained open for a time >1.5sec and the system is blocked. A specific reset procedure is required, even after the safety chain has been closed.1) Release the final limit switch (or Safety Gear or OSG) closing the safety chain (SE3) and cancel fault in the PlayPad “Faults” Menu (Reset SE3).
2) Check Positioning System;
3) In case of Electric Controller, check Brake Hold. In case of Hydraulic Controller, check Valve circuit

a) If the lift is on a different floor than the one where the fire was detected, all calls logged to/from this floor are canceled.
b) If the lift is at the floor where the fire was detected, the controller stops the door opening, closes doors (if open upon fire detection), and sends the elevator car to a safe floor previously set. – “EN8173” to YES (Fire evacuation procedure). The following evacuation rule is applied:
a) (If the fire detection is not active on the Main Floor) the car is moved to Main Floor.
b) The car is moved to an alternative floor, where the fire sensor is not activated

In case of DMG Rope Encoder or ELGO
Check:
1) Slowing distances to the floor;
2) The arrival distances to the floor (parameters RLD and RLS);
3) The low speed setting (valve/electronic control unit parameter)
4) The valve circuit.
34Anti-nuisanceXXXWarning“Anti-nuisance” function activated: too many simultaneous calls from the lift car. Calls are canceled. (With the “anti-nuisance” function active) An excessive number of car calls have been activated without:
– The photocell being interrupted (in the case of automatic doors);
– The landing door having been opened (in other cases).
Cabin calls are cancelled and the lift continues to be available
Change the number of unwanted calls in the Anti-nuisance parameter on PlayPad / Special Features / Anti-nuisance fault (https://dido.dmg.it/knowledge-base/controller-p40/#special-features-menu).
35Lift not avalaible100WarningThe lift cannot serve calls and therefore is not considered for multiplex calls.Photocell or door opener active for more than twice as long as the standby time with open doors (e.g. for people standing in front of photocells or door skids).
In these cases the lift makes 3 attempts to start. If they fail, the lift is unavailable for floor calls for 1 min.
Check:
1) The presence of physical obstructions at the photocell;
2) Increase door closing time (https://dido.dmg.it/it/knowledge-base/controller-p40/#doors-menu)
35Lift not avalaible200WarningThe lift cannot serve calls and therefore is not considered for multiplex calls.No signal from the safety contact upstream of Point #4 (preliminary floor locks). The manual door may not be closed.
In such cases the lift makes 3 attempts to start. If failed, the lift is unavailable for floor calls for 1 min.
Check:
1) Preliminary floor doors SD1-SD2;
2) The correct closing of the landing doors
35Lift not avalaible10AlertThe lift is unavailable and cannot serve calls.Car light power failure or cabin light failure, for all types of systems. The system is stopped with open doors. The error is active if the LE input is active (can be checked via PlayPad diagnostics, I/O status menu page 1 https://dido.dmg.it/it/knowledge-base/controller-p40/#i-o-status-menu)Check:
1) Presence of voltage on the power supply line;
2) Presence of light in the car.
36Phase sequence XXXAlertWrong sequence in input phases. Could be detected even during system shutdown.Wrong sequence in input phasesCheck the right sequence of phases or swap two phases on power input terminals L1-L2-L3. It is possible to check the input RPH status via PlayPad, I/O status menu, Playboard IN/OUT page 4 (https://dido.dmg.it/it/knowledge-base/controller-p40/#i-o-status-menu ). If the input is active, the phases are faulty
37Low batteryXXXWarningLow charge on 24V battery.Possible causes of the fault:
1) Batteries disconnected or not functioning;
2) Batteries no longer capable of maintaining an adequate charge. This usually occurs four years after the first charge (the date of first charge is marked on the battery label);
3) Battery charger not working (CHAR board).
Check:
1) The status of the LEDs on the CHAR board (YELLOW: test in progress; GREEN: batteries OK; RED: low batteries or disconnected). The test can be forced by pushing the button next to the LED on the CHAR board. If the test fails with the batteries connected, check the batteries one by one;
2) The voltage of the batteries. The voltage value must be higher than 12V. Otherwise, replace the batteries;
3)Measure the voltage on the power cables of the batteries (disconnected). The voltage must be at least 27V. If lower, replace the char board or check the loads connected to the batteries.

40Access to PitAlert + ResetPit access alarm (EN81-20 standard)The floor door on the lowest floor was opened to access the pit (manual unlocking of the floor door with monostable or bistable contacts). According to the EN81.20 code, this access causes the system to block and requires a specific reset procedure The same error can also be activated on systems without a landing door release contact, following:
a) Activation of the STOP in the pit
b) Activation of INSPECTION mode from the inspection box
c) Opening the safety chain between points #1 and #0 (LED S1 off and S0 on on the PlayPad)
d) Involuntary opening of the SE1 circuit (false contact, loose wire…)

In all these cases, error 38 is also activated (subcode 1 – Point #1 open)

After resetting the STOP button in the pit/top of car and switching to “Normal mode”, perform the specific error reset in one of these ways:
– Via specific menu on the Playpad (https://dido.dmg.it/knowledge-base/controller-p40/#faults-menu)
– 3 consecutive activations of the landing door switch (where the double contact is present)
– 3 consecutive activations of the down button on the inspection panel on the controller

40Access to ShaftAlert + ResetPit access alarm (EN81-21 standard)A floor door has been opened to access the pit or car roof (manual floor door release with monostable or bistable contacts). Because the system includes small spaces in the headroom and/or pit, according to EN81.21, this access is a reason for system lockout and requires a special reset procedure.After resetting the STOP button in the pit/top of car and switching to “Normal mode”, perform the specific error reset in one of these ways:
– Via specific menu on the Playpad (https://dido.dmg.it/knowledge-base/controller-p40/#faults-menu)
