High Temperature Alarm
The temperature value above which the alarm will be detected is configured as described in paragraph
10.13.1. The high temperature condition will not allow the elevator to start if detected when elevator is
stopped. If the elevator is running and a high temperature alarm is detected the following Stop Relay Delay
will apply:

Test Functionality
To test that the W4005V46-SYSx /B system is correctly wired to control the elevator, users can press the Test
button on the front lid. There are two types of tests available:
10.16.1.
Simple Test
To test the correct functionality of the microprocessor and LEDs, a simple test can be performed. This test
can be performed when the system is either running or stopped. When the TEST button is pressed and
released all the LEDs will toggle.
10.16.2.
Extended Test
An extended test can be performed to test all the relays, LEDs and microprocessor operation. This test can
be performed by pressing the TEST button
twice
in quick succession. Make sure to press and release the
second time while the LEDs are lit from the first press, i.e. when the simple test is running. All the LEDs will
toggle after which the Alarm/Fault relay will turn ON and then OFF after 1 second. The Stop relay will open
and the elevator should stop if the W4005V46-SYSx /B system is wired in correctly. The Alarm/Fault relay
will also open at his stage and stay in the open state until the fault is reset. All the LEDs will keep toggling
after the machine has been stopped. The system fault must be cleared before the elevator can be started
again after the extended test.
The Extended Test can only be started when the W4005NV46AI /B controller has been
previously calibrated and the elevator is running normally without any alarms. If the controller
is in any other state or if at least one alarm is present, only the Simple Test can be performed.
Make sure that the machine is empty of material prior to performing an extended test!

Normal Machine Start / Stop
Under normal conditions the elevator should be started by the operator pressing a start button on the
control panel. The run signal (24VDC) must be constantly present on pin 16 and also the contactor feedback
must maintain 0VDC voltage across the terminals 17 and 18 of the W4005NV46AI /B controller throughout
the duration of the elevator running state.
