2.6.3. Return water flow switch setting
Introduction
The mechanical flow switch is pre-set at delivery to 8 liters/min at 0.2 MPa water pressure.
If the water pressure exceeds 0.2 MPa, the setting cannot be done with the graduation on the
window name plate, as the pressure affects the measured flow. Please perform the setting as
described in the following procedure.
Settings
The procedure below details how to set the mechanical flow switch.
Action
Note
1. Open the solenoid valve on the water inlet.
2. Water flow is indicated on the scale of the flow
control valve.
3. Adjust the water flow to the level where the
Flow switch shall give alarm. Use the red
adjusting knob on the scale of the flow control
valve.
Detailed in section
4. To adjust the set flow on the mechanical Flow
switch, remove the grommet on the upper
cover and rotate the flow adjusting gear by
using a flat screwdriver.
Turning clockwise will increase the set flow
and turning counterclockwise will decrease
the set flow.

A: Flow switch
5. Depending on initial value, increase or
decrease the set value until the
g_flow_ok
changes, by observing the
Process Signals
window
on the Robot Teach Pendent.
NOTE!
The indicated flow level may differ from real
flow as the flow switch is affected by the water
pressure.
