Calibration SQL361B.. , SQL351B.. In order to determine the disc position fully closed “0%” or fully open “100%”, calibration is recommended on initial commissioning of modulating type actuator. Prerequisites · Actuator is mounted on butterfly valve · Rotate the actuator to the half-open position using the handwheel · Housing cover is removed SQL351/361B25..B50 Calibration 1. Press button S3 for 5 seconds to start calibration 2. Actuator moves to «100 %» stroke position (valve opened) automatically 3.

Orientation The valve and actuator can be assembled on site. There is no need for special tools. Upright to horizontal Commissioning notes When commissioning the motorized butterfly valves, always check wiring and test the functions. This also applies to any additional components fitted, e.g. auxiliary switch. Warning To avoid pressure shocks on the butterfly valve, the VKF42.. must be driven to its fully open position either manually or via positioning signal prior to activating the pump(s).
Warranty The engineering data specified in chapter "Equipment combinations" (page 3) are only guaranteed in connection with the Siemens butterfly valves listed. Note When using the actuators in connection with butterfly valves of other manufacture, correct functioning must be ensured by the user, and Siemens will assume no responsibility.
