Initial Start-Up; Mounting And Installation; Adjusting The Incomplete Device - Walther Systemtechnik WDV-01 Assembly & Instruction Manual

Rev. 1.2

5 Initial Start-up

5.1 Mounting and Installation

IMPORTANT
We recommend adding a maintenance unit to the control air.

5.2 Adjusting the Incomplete Device

IMPORTANT
In order to ensure optimal operation of the valves, make sure that the air supply
pressure is set to approx. 6 bar.
The lubricant feed pressure should not exceed 200 bar at the input. To ensure this,
check the pressure conversion ratio of the lubricant feed pump. The feed pressure may
be reduced by means of an air pressure control valve (The use of an air pressure
control valve may be advantageous, although it is not imperative as long as the 200
bar are not exceeded).
IMPORTANT
All dosing valves are tested by the manufacturer prior to shipping. Due to testing, resi-
dues of test liquid may be found inside the valve.
1) Make sure that the lubricant feed hose is filled with lubricant and all air is removed. Then connect
feed hose and air connectors according to drawing.
2) For first operation, set valve to maximum dosage (i.e. turn adjustment screw to outmost position).
3) If the adjustment screw cannot be turned, change position of change-over-valve. The adjustment
screw should now be unlocked.
4) Execute a first shot of lubricant. Then set the adjustment screw to the desired grease quantity.
5) Keep the distance from the metering valve to the greasing point short. This allows for improved
metering precision and repeatability.
6) The minimum cycle time depends on the viscosity of the lubricant, as well as on the lubricant feed
pressure.
7) The dosing valves with support bracket can be fastened with four M5 screws.
8) The dosing amount can be adjusted via the dosing screw.
9) When installing the (optional) dosing sensors, please consider that there are 2 switching points per
magnetic field.
