1. Warnings, legal information and notes to CE-marking
This manual gives general guidelines on how to install and operate a gen-set using
the product MPC-1. Installing and operating a gen-set implies generation of
dangerous current and voltages, and therefore this should be done by qualified
personnel only. DEIF takes no responsibility for operation or installation of gen-sets or
other systems using the described methods in this manual. If there is any doubt about
how to install or operate the gen-set the company responsible for installation or
operation must be contacted.
MPC-1 is CE-marked with respect to the EMC directive for residential, commercial and
light industry plus industrial environment.
MPC-1 is CE-marked with respect to the low-voltage directive for 300 V class
systems, protection class III and pollution degree 2.
Take precautions against electrostatic discharges when service or installation
operations are done. The unit is protected against electrostatic discharge in normal
operating situations, but service or installation operations can cause unforeseen
electrostatic discharges.
2. Parameter setting
In the following, use the blank column "commissioning value" to write down your own
settings.
2.1 Select parameter menu
By pushing the buttons "V" and "SET" simultaneously a swap between mode "auto"
and "parameter" can be carried out. The functions of the buttons "LOG", "V" and
"SET" are changed to the indications below the buttons, i.e. "LOG" turns to "P", "V"
turns to "5" and "SET" turns to "8". The "auto" LED will flash.
In parameter mode, all set-points and timers can be changed.
If no parameter setting inputs has taken place for 30 secs, the MPC-1 will return to
"auto" mode.
To make key-in of values easier, the function is equipped with a "sweep" function. By
holding a button down, a fast sweep through values can be carried out.
The first thing shown is the software version. To continue, press "P".
2.1.1 ”P” pushbutton
Stores the keyed in display parameter value, jump to the next parameter.

Programming manual MPC-1
4189340103E
If the display value has been changed via the "5" or "8" buttons, the new value can
be stored by pushing the "P" button once. If the button is pushed twice, the display will
jump to the next parameter.
2.1.2 ”5” pushbutton
Steps the chosen displayed value up one unit (within allowed limits). Digit is chosen
by moving the cursor.
2.1.3 ”4” pushbutton
Analog values: Moves the cursor to the next digit
Binary values: Swap of different functions (e.g.: ON/OFF)

3.7 Mains 3-phase voltage supervision
In parallel with mains, this function is essential. Should a mains failure occur, the
parallel running generator must be disconnected from the mains. Dependent on the
modes chosen, the genset will be switched into idle run or emergency power run.
