Unit limitation -
Electrical wiring
(optional) The machine's microprocessor allows for the limitation of capacity by means of two separate criteria:
Q
Load limitation
The load can be varied directly by means of 4-20 external signal or directly from a BMS. The sig-
nal cable must be directly connected to terminals 37 and 38 of the M5 terminal board. The signal
cable must be of the shielded type and must not be laid in the vicinity of the power cables, so as
not to induce interference with the electronic controller.
Q
Current limitation (optional)
This option, if installed, allows for the control of machine load according to current absorbed. Con-
nect a switch, timer, clean BMS to terminals 37-39 on the terminal board M5. Once the digital
input is closed, the microprocessor will limit the current absorbed by the machine according to the
command set point set. The enabling of this control needs enabling by means of a clean contact,
using terminals 6-9 on terminal board M5.
Caution: The two options cannot be enabled simultaneously. Setting one function excludes the other.
