Type 8718, 8719 / 8708, 8709
Installation and Start-up
noTe!
During prolonged operating pauses, drain the fluid out of the LFC / LFM and flush with compressed air.
To do this, the device must be actuated so that the valve is open.
•
Ensure that the calibration pressure of the device is not exceeded.
Too high a pressure within the LFC / LFM will cause irreparable damage to the device.

Danger!
risk of injury due to electrical shock!
•
Before removing covers,
•
Observe applicable accident prevention and safety regulations for electrical equipment!
Warning!
risk of fire and ignition due to electrostatic discharge!
If the device is electrostatically charged, highly flammable fluid vapors may ignite if a discharge occurs.
•
To prevent an electrostatic charge, connect the housing to the function earth (FE) via the shortest possible
cable length (cross-section as large as possible).
danger from electromagnetic fields!
If the FE connection is not connected, the conditions of the EMC Law are not being satisfied!
•
Connect the housing to the function earth (FE) via the shortest possible cable length (cross-section as large as
possible).
noTe!
important information for the problem-free functioning of the device:
The GND or earth cables for all signals of the LFC / LFM must always be fed separately to the LFC / LFM.
If all GND signals are bridged directly on the LFC / LFM and only one common cable is fed to the control, signal
displacements and interference of the analogue signals may occur.
→
Connect the function earth (FE) to the indicated screw, e.g. with the aid of a ring tongue.
switch off the power supply and secure to prevent reactivation!
