10.25.2 PE Busbar
Two rails are fitted to the left and right side of the terminal strips and parallel to them on the
unit's rear side. Connect all shieldings to these rails. Also connect the PE to this point from
the outside.
10.25.3 Control Cabinet Wiring
The low-voltage cables from and to the ETAMATIC OEM should not run in parallel to the power
electronics' in and out conductors in one cable duct.
Frequency converter cables and switches/contacts carrying high inductive or capacitive firing
rates are particularly critical. Therefore, avoid routing parallel to the drive cables of solenoid
valves, ignition transformers, servo motors and similar devices.
Although this device exceeds all relevant EMC standards in some respects, suitable wiring is
essential to ensure that the entire system operates smoothly in all conditions.
Shielding of supply lines out of the field:
The best method of connecting supply lines out of the field (e.g. potentiometer line) is to con-
nect them directly (without additional terminals).
If you need additional terminals, you must connect the shielding beside this terminals
Avoid long distances in the cable duct.
10.26 Run to Shut-off Limits
Press key (Hand)
Run to firing rate point to be checked (key and )
Wait until the system has run to that point
Entering passwort
Mode selector switch to "Setting”
Press key 1x (Setting)
Adjust setpoint value of the continuous channel in the air deficiency direction until the actual
value feedback has changed by the set number of points (monitoring band)
Check firing
Reset setpoint value to the next continuous channel in air deficiency direction.
Check firing
Repeat, until all continuous channels are checked at their limits.
Check the shut-off limits at the DPS output of the ETAMATIC OEM .
