Use Arrow Keys to scroll through language and pressure options.
Press OK to accept.
Allows user to set pressure output between 0-10 Bar for both Min
and Max demand signals.
This makes it possible to have a low signal giving a high output and
vice versa.
Scroll through numerical values
0-7 to set speed.
0 = fastest, 7= slowest
N.B Response will vary with load volume.

Set up
With Air supply on, Set the input signal to the required Max and Min
values. Use the Arrow Keys to fine tune the VP51 to the host
system.
Display function that provides feedback facility for user information.
Green LED is normally permanently on when power supply is
present. This function allows user to set Green LED to flash when
output pressure is outside a specified window.
Red LED is normally off. Can be set to flash if output pressure does
not reach the required value within a specified time limit. Red LED
will also flash when running in local control functions.
Local control function enables the user to manually set output
pressure using arrow keys. To accept command press OK. This will
display an output pressure warning. To return to Remote Control
press C followed by OK. This will display the main menu structure.
Display function that shows device ID , serial No. Also contains
password change facility Web address of distributor.
Provides option to resort factory defaults.
Enter a 4 Digit password and press OK . If password is inactive
press OK to enter.
To set the proportional gain first set the integral gain to 0, then
adjust the proportional gain to give the best response time for your
application. Once set adjust integral gain to stabilise this output.
0 = low, 7 = high.
Scroll through numerical values 0-7 and press OK to accept. This
function allows the dither amplitude to be adjusted according to the
application.
0 = dither off, 7 = dither max.

Warning
These products are intended for use in industrial compressed air systems only. Do not use these products where pressures and
temperatures can exceed those listed under ‘Technical Data’.
Before using these products with fluids other than those specified, for non-industrial applications, life-support systems, or other applications
not within published specifications, consult NORGREN.
Through misuse, age, or malfunction, components used in fluid power systems can fail in various modes. The system designer is warned to
consider the failure modes of all component parts used in fluid power systems and to provide adequate safeguards to prevent personal
injury or damage to equipment in the event of such failure.
System designers must provide a warning to end users in the system instructional manual if protection against a failure mode
cannot be adequately provided.
System designers and end users are cautioned to review specific warnings found in instruction sheets packed and shipped with these
products.
