4.4 Adjustment
The standard start delay and the standard stop delay of the
extraction fan(s) are 0 seconds. This means that the
connected fan will immediately start running when the
welding starts and will stop immediately after the (last)
welder is finished. If desired, these pre-set times can be
adjusted by changing the settings of the timer PC board (Fig.
4.2). The timer PC board consists of the following
components:
A Potmeter 1 (start delay)
B Potmeter 2 (stop delay)
C Status leds
D Fuse 2A
E Connection WCS, AST, Filter
F Connection 24 VAC
G Relay contact

4.4.1 Start delay
The start delay can be set from 0 to 5 seconds (standard 0
seconds). To adjust the start delay, proceed as follows.
• Adjust Potmeter 1 (Fig. 4.2A) to the desired number of
seconds.
4.4.2 Stop delay
The stop delay can be set from 0 to 300 seconds (standard
0 seconds). To adjust the stop delay, proceed as follows.
• Adjust Potmeter 2 (Fig. 4.2B) to the desired number of
seconds.
When setting the installation, the functioning of the timer PC
board can be checked by the status leds Power, Input and
Output (Fig. 4.2C) on the timer PC board.
By applying the weldling cable sensor WCS to the ground
cable of a welding machine, the CB-WCS functions fully
automatically.
The CB-WCS does not require any specific maintenance.
In most cases, a stop delay of 20 seconds will be
sufficient.
