Siem ens Modulating control valves with magnetic actuator‚ PN 16 CA1N4465en
Building Technologies 2018-02-05
The MXG461S.. magnetic valves are factory-calibrated
at 0 % and 100 % stroke.
When commissioning the valves, however, (especially
under extreme conditions of use) there may still be
some leakage via control path A ↑ AB with a 0 %
stroke control signal (DC 0 V, DC 2 V or DC 4 mA).
In this case, the valve can be recalibrated simply and
quickly:
1. Set hand wheel [2] in AUTO-position.
2. Activate calibration using a pointed pin (ø 2 mm) by
pressing the button in the opening [3] once.
3. While recalibration is in progress, the LED [5] is
flashing green for approximately 10 seconds.
The valve will be briefly closed and fully opened.
If the electronics module is replaced, the valve’s
electronics must be recalibrated. For that, the hand
wheel must be set to AUTO.
The two-color LED display indicating operating status can be viewed by opening the
cover of the electronics module.
LED Indication Function Remarks, troubleshooting
Green Lit Control mode Automatic operation; everything o.k.
Flashing Calibration
In manual control
Wait until calibration is finished
(green or red LED will be lit)
Hand wheel in MANUAL or OFF position
Red Lit Calibration error
Internal error
Recalibrate (operate button in opening 1x)
Replace electronics module
Flashing Mains fault Check mains network (frequency or voltage
outside operating range) or valve blocked
Both Dark No power supply
Electronics faulty
Check mains network, check wiring
Replace electronics module
As a general rule, the LED can assume only the states shown above (continuously red or
green, flashing red or green, or both off).
