OPERATION
♦ WHEN WS-LD IS TRIGGERED
:
When WS-LD is triggered, it will sound an alarm and trigger VCM to shut-off the valve automatically
and send report signal to the dialer.
<NOTE:>
" If VCM fails to shut-off the valve successfully, VCM will sound alarm for 3 mins. During these 3
mins, if Red Tack Switch on VCM is pressed, the alarm can be stopped immediately.
" Whether the Valve shut-off is a success or failure, VCM will report the condition to dialer.
" When WS-LD condition is cleared, the valve will remain shut until it is opened again, either
remotely (by RS) or manually (by VCM’s Rock Switch).
♦ USING RS TO OPEN/SHUT THE VALVE (REMOTELY):
When RS ‘ON’ switch is pressed, VCM will open the valve.
When RS ‘OFF’ switch is pressed, VCM will shut off the valve.
<NOTE:>
" Whether the Valve open or shut-off is a success or failure, VCM will report the condition to dialer.
♦ OPEN/SHUT OF VALVE BY VCM (MANUALLY)
:
The Valve will be opened by sliding the VCM’s Rock Switch upwards.
The Valve will be shut by sliding the VCM’s Rock Switch downwards.
<NOTE:>
" Whether the Valve open or shut-off is a success or failure, VCM will report the condition to dialer.
REMOVING FAULT DEVICES
Step 1. Press and hold the Red Tack Switch for 15 secs.
Step 2. VCM sounds a melody tone “do-di”
Step 3. VCM will be cleared of all fault devices.
<NOTE:>
" The Fault LED will go ON to indicate an out-of-order condition. Once the fault condition has
been restored, the LED will go off automatically.
" This function should only be used when WS-LD’s faulty condition cannot be restored. This will
enable the VCM to remove the previously learnt WS-LD devices.
