a) It is necessary to activate the reset key. All
inspection/recall signals (868,869,870) must be active
which shows normal operation. All the safety circuit
signals (120, 130, 140) must be active. In this case, when
reset key input (IPR) on the pit board is activated, the
system will turn to normal mode.
b) Another option for back to normal operation from pit
inspection, while all inspection/recall signals
(868,869,870) are in normal mode and all doors are
closed (120, 130, 140 signals are active), apply the
following procedure at the lowest landing call button: “3
x short press → 1 second wait → 3 x short press → 1
second wait → 3 x short press”. If the reset is successful,
the button led will start flashing and the system will turn
to normal mode.
‼ NOTE: For duplex lifts only option a) is allowed.
An electrical key operated switch shall be provided
on the lowest landing for each lift separately.
11. Error Codes, Possible Reasons and
Solutions
➢ H1: FAIL TO LOCK DOOR. 140 SIGNAL IS
MISSED
After door close command, if 140 signal is still OFF
within the value inside “7.9: DELAY BEFORE DOOR
CLOSING RETRY” parameter, this error is raised.
The time value should be increased if it is entered so low.
Safety circuit needs to be checked.
➢ H2: FLOOR TO FLOOR MAX TRAVEL TIME
ELAPSED
This error is raised if the car couldn’t reach to a new floor
within the time value inside “2.8: MAXIMUM
TRAVEL TIME BETWEEN FLOORS” parameter.
The time value should be increased if it is entered so low.
If the value is enough, ML1-ML2 signals need to be
checked while car is moving.
➢ H3: DOOR IS NOT CLOSED FOR A LONG
TIME
If the door couldn’t be closed (140 signal is OFF) within
the time value inside “7.7: DOOR OPEN ERROR”
parameter, this error is raised and the system goes to out
of service. This should be set enough in order not to get
error unnecessarily. Although the doors are closed, if you
still get an error, the door contacts and 140 signal on the
controller board needs to be checked.
➢ H4: CAR CAN’T HOLD. PLEASE CHECK
MOTOR PARAMETERS
During the auto tuning, if motor turns more than a certain
value, this error is raised. The motor parameters need to
be checked.
➢ H5: BOTH LIMIT SWITCHES UP&DOWN
ARE OPEN
If both limit switches have OFF position at the same time,
this error is raised.
Under normal circumstances, one of the limit switches
can be OFF. At least one of them must be at ON position.
If car is at the bottom floor, 818 is ON. If car is at the top
floor, 817 is ON. Magnetic switches, magnets and their
put in order need to be checked.
➢ H6: TOP LIMIT SWITCH CUTS OFF WHILE
RUNNING DOWN
818 magnets are used at the top floor and 818 signal can
turn to OFF position only while going in the up direction.
The signal can’t turn to OFF position while going down.
If this occurs, this error is raised.
You should be sure that the red and white side of the
round magnets are put in order correctly.
➢ H7: BOTTOM LIMIT SWITCH CUTS OFF
WHILE RUNNING UP
817 magnets are used at the bottom floor and 817 signal
can turn to OFF position only while going in the down
direction. The signal can’t turn to OFF position while
going up. If this occurs, this error is raised.
You should be sure that the red and white side of the
round magnets are put in order correctly.
➢ H8: LOW DC BUS VOLTAGE
If the mains supply is lower than the working voltage,
this error is raised. Check the mains supply from L1, L2,
L3 inputs.
➢ H9: HIGH DC BUS VOLTAGE
This error is raised if DC-bus voltage is higher than the
limit voltage. When the mains supply is increased upper
than a value, this error is raised.
Check the mains supply from L1, L2, L3 inputs. Phase to
phase voltage shouldn’t be more than 440V. The
connections of brake resistor need to be checked.
