2.6.5 Setting of electrical proportional valve (option)
Introduction
The electrical proportional valve is available as an option.
The output pressure from the proportional valve is set by a voltage input signal, 0
- 10 VDC.
The output pressure range is 0.005 - 0.9 MPa.
I/O configuration
The following has to be done in order to configure the system to automatically feed
the electrical proportional valve with 24 V only, when there is a sufficient air pressure
indicated by the air pressure switch. If there is not enough pressure, the electrical
proportional valve works continuously and the lifetime may be shortened.
The related input and output is gx_air_ok and gx_epvalve_on , where x represents
the actual gun. The example below shows the setting for gun 1.
Note Action
Create a digital output signal named g1_epvalve_on
on unit SWBOARD1 and unit mapping 14 .
1
Create a cross connection between g1_air_ok and
g1_epvalve_on .

Setting
Normally the pre-set values are used. But if other settings are desired, do as
described below.
The procedure below details how to set the proportional valve.
Note Action Mode
Make sure that the 12-24 VDC power
is connected. 1 Preparation
The keys are locked after
the power is turned on and
cannot be operated.
Loc is
indicated on LED when the
keys are pushed.
The indication Loc flashes on LED by
pushing the DOWN key for two
seconds or more.
The key locking function is released
by pushing the SET key here.

ing
F_1 is indicated on LED. Press the SET key. 3 Min. pressure
setting
The min. pressure is equal
to 0 VDC input signal. Set the required min. pressure by us-
ing the UP and DOWN keys. 4
F_2 is indicated on LED. When finished, press the SET key. 5
The max. pressure is equal
to 10 VDC input signal. Set the required max. pressure by us-
ing the UP and DOWN keys. 6 Max. pressure
setting
P_1 is indicated on LED. When finished press the SET key. 7
