Commissioning notes
The manual adjuster must remain secured with anti-tamper screws as
factory delivered.
When removing anti-tamper screws approval for the safety function to
DIN EN 14597 ceases.
Valve stem retracts: valve opens = increasing flow
Valve stem extends: valve closes = decreasing flow
When commissioning the system, check the wiring and functions, and set
any auxiliary switches and potentiometers as necessary, or check the
existing settings.
The actuator is driven to OPEN (valve open) until the red clamp, that fixes a
stroke position of ca. 50% can be easily removed. Voltage must be applied
to either terminal 21 and Y1 to drive to OPEN, or voltage to G-G0 as well
as Y > 70%.
The safety function is only enabled after the red safety clamp is
removed.
