13
Motor
temperature
sensor
Inputs TH1 or TH2 of motor
temperature is activated (NC contact)
Cod 1: TH1 open
Cod 2: TH2 open
Cod 3: TH1 and TH2 open
Cod 10: Door’s thermic input (TOC
board)
Check inputs (TH1, TH2), sensor
connections and the state of the motor’s
temperature sensor.
Cod 1 Check TH1 input
Cod 2 Check TH2 input
Cod 3 Check TH1 and TH2 inputs
Cod 10 Check door’s thermic input on
TOC board’s M16 Connector.

Parameters
memory
Fault in the Eprom parameters
memory
Reset, re-enter and record all
parameters
15
Final limit switch
When it is reached the final limit
switch (or Safety Gear or Overspeed
Governor limiter trip), the input SE3 is
active (NC contact).
After delay of 1,5 s the error remains
in memory, even after deactivation of
the signal, and inhibits the landing
calls and the car movements, until
special reset Menu "Errors" is made
(Reset SE3).
1- Release the final limit switch (or
Safety Gear or OSG) closing the
safety chain (SE3) and cancel fault
in the “Error” Menu (§ 5.3).
2- Check the connection of the NC
contact between SC2 and SE3
terminals
16
Fire detection.
In case of fire sensors installed, this
fault indicates that one or more
sensors are active
Check fire sensor input(s)
17
Safety 4 open
during travel
Safety chain open before input SE4
while car travelling.
Landing calls and the car movements
are cancelled
On the PlayPad Led SE4 is off.
Check all contacts between the terminals
SD1 and SD2 (Preliminaries floor doors).
18
Safety 6 open
during travel
Safety chain open before Input SE6
while car travelling.
landing calls and the car movements
are cancelled
On the PlayPad Led SE6 is off.
Cod 5: floor locks
Cod 6: car door
Check all contacts between the terminals
SD2 and SD3 (floor locks).
Check all contacts between the terminals
SC4 and SC5 (car door).
Check all contacts between the terminals
SC5 and SE6 (Protection device 81-21).
19
Low tension
during movement
Motherboard power below 17V (this
fault disappears when the 24V is
restored)
Cod 0: Main power Input
Cod 1: Overcurrent on VCAB
Cod 2: Overcurrent on VMR
Cod 3: Short Circuit on VCAB
Cod 4: Short Circuit on VMR
Cod 230: Missing 230 V, controller is
powered with batteries
Check the network, the supply voltage to
the transformer primary, the presence of
24V and the consumption of the circuit.
Cod 230 check backup circuit (R230) if
present or shunt on J8 of CHAR board.
