As soon as the system has reached steady operating conditions,
however, no later than after 10 hours' operation, the system is stopped
and all pipe connections and fixing devices checked and, if required,
tightened (various parts may get loose during transport or installation).
Minimum programming of the FCM 300 drive motor
There are two ways to program the FCM 300 drive motor (please also
refer to FCM Design Guide or Operation Manual):
• Using the Danfoss "Local Control Panel" (LCP 2) or
• The Danfoss PC software
Both solutions connect into the RS 485 interface of the drive motor
(X 100).

Par. 215, preset reference 1:
The setting of this parameter determines the set point of the PID-
controller and thus the system pressure. The setting is expressed as a
percentage of the feedback range programmed in par. 414/415.
Example:
transmitter range 0...160 bar, desired set point 70 bar: 70/160 = 0,4375
Program 43,75% in parameter 215
To program the FCM 300 according to the additional wiring described
above, please refer to the FCM Design Guide or Operation Manual.

In general, the FCM 300 drive motor comes with a standard factory set-
ting. A few parameters must, however, be set to adapt the FCM to the
Plug&Spray
setup as described below (deviation from factory setting):
To start with, please set the language in parameter 001 to English if
necessary.

When finished programming the FCM 300, make sure to press
START before unplugging the LCP 2 or the PC software. Then
disconnect power; otherwise the system will not start when
applying power next time.
