MAINTENANCE
Special case: Actual value is to be output via the analog output for reading
Submenu item “Filter” must be activated via the keypad on the VISIC100SF to enable
transfer of the values to the central computer in the control station.
By activating submenu item “Filter”, the actual value is not only shown on the display but
also output on the analog output.

NOTE: Check correct wiring of malfunction relay
The test value is shown as actual value if the malfunction relay is not connected and
causes an incorrect ventilator control.

The gas sensor contains sulfuric acid.
▸ When taking the gas sensors out, avoid any damage by a pointed or sharp object.
Package the gas sensors carefully and securely when damaged and dispose of as
hazardous waste.
