gives this error. The car should be stopped by pressing both buttons together. After contactors are dropped, the fingers
should be released.
- If this error is in normal mode, brake resistor connections should be checked.
- The safet circuit may be cutting during movement.
17-Inconsistent encoder speed reading: If the acceleration exceeds 10 m/s2 for 5 times consecutively, this error
occurs.
- Mounting of encoder should be checked. Encoder may be slipping while turning.
- Encoder cable connection and earth connection should be checked.
- Encoder cable should be at least 5 cm far from the cables which carries 220V AC voltage.
18- Car overspeeded: this error is faced with if the speed information from the encoder is above the calculated
speed.
- Encoder connections must be controlled. Motor parameters must be controlled.
- The elevator’s load balance must be set correctly. Load balance must be controlled by putting half-load into the car.
- Speed PID gains that are in PID control settings may be insufficient. Gains must be raised.
- Safety circuit should be checked. While the car is moving, if safety circuit is cut suddenly, iy may give this error.
19- Could not reach required speed: If motor can not reach to the reference speed in 5 seconds, it gives this
error. Though sufficient power is transmitted to the motor and it doesn’t reach the desired speed, this error is met.
- Motor parameters must be controlled. Encoder connections must be controlled.
- Load balance must be controlled by putting half-load into the car.
- Speed PID gains that are in PID control settings may be insufficient. Gains must be raised.
- Motor unloaded current that is under motor plate information must be set %20 in geared machines.
- Try to move the car in asynchronous machines in inspection mode with open loop. If there is no problem in the open
loop, check the connections of encoder and ENCI board.
20-Encoder connection fault: When wrong info. comes from encoder, this error is given. This error is received
only in synchronous machines.
- The connections between encoder and encoder board should be checked.
- Encoder type parameter should be checked.
21- At least one phase missing: L1,L2,L3 and N inputs must be controlled.
- One or more of the phases are not coming, or the voltage value may be low.
22- 3-Phase sequence is wrong: Phase L3 or L1 must be replaced with Phase L2.
23- 24V supply voltage too low: Measure ARCODE 24v inputs. This error is taken if the value measured is below
20 VDC.
- Control 24V power distribution unit (transformer) output. It must be 19 VAC in transformer output. If SMPS is used
instead of transformer the output voltage of SMPS must be 24VDC.
- If voltage is below 19 VAC, either the transformer is out of order or there is a line that used over current in 24VDC
outputs to decrease voltage.
24-Car was over top floor level: When the car passes ML2 of the top floor, it gives this error.
- The position of door zone magnets may be changed.
- Position of 818 magnet may be changed. “Shaft learning done” parameter should be adjusted “No”. Then, shaft
learning process should be performed again.
- If ML1/ML2 signal or signals are cut when elevator reaches top floor it can give the same error. The magnetic
switches must be checked.
