PLC Protocol Selection
The W4005NV46AI /B supports
two of the industry’s major Industrial Ethernet protocols: ProfiNet and
Ethernet/IP.
10.13.3.
Fixed Settings
There are a number of settings that are fixed within the unit and cannot be changed. It is very important that
the user is familiar with these settings when operating the product. Please refer to the Alarms and Shutdown
section for more information.

W4005NV46AI /B Calibration
The W4005NV46AI /B unit is delivered in a Non-Calibrated state. This is distinguished by both the
ALARM/STOP LED and Alarm relay toggling every 1 second. The W4005NV46AI /B
MUST
be calibrated before
it can be used to control the elevator. This procedure is the same for both Single and Differential speed
modes
The following steps must be executed to calibrate the W4005NV46AI /B controller:
a)
Press and hold the TEST button for 5 seconds
–
This will start the calibration process and the
W4005NV46AI /B will now be waiting for the motor run signal to be applied. In this state the
W4005NV46AI /B Alarm/Stop LED will carry on toggling, but the Alarm/Fault relay will Close
b)
Operate the START button on the motor starter. This provides a motor run signal to the
W4005NV46AI /B terminal 16 which will cause the Stop relay to be energised and allow the machine
to start. The contactor N/C auxiliary contact must be used to supply the feedback signal back to the
W4005NV46AI /B controller. ALARM/STOP and ELEVATOR RUN LEDs will be flashing at this point.
c)
The Calibration procedure takes 20 seconds plus the start-up delay (see paragraph 10.13.2.2 for more
details).
d)
When the Calibration procedure is complete the unit will go into normal operation. Any change of
speed or misalignment or temperature beyond the allowed levels will now cause the appropriate
ALARM and STOP action
If it is necessary to re-calibrate the W4005NV46AI /B, please repeat the steps above.
NOTE:
To clear the calibration press and hold the Test button for 10s. Then reset the power to the device.
This will clear all calibrated values.

Alarms and Shutdown
Each Alarm Source (sensor) has its own stop delay timer. As soon as the alarm condition is detected, the
corresponding LED is lit immediately on the front of the unit. The stop relay will open after the stop delay.
All timers are cumulative, so that if an alarm condition is repeatedly detected and cleared (belt wandering)
the elevator will eventually be stopped if the sensor is staying in an alarm state more than in healthy state.
