The management of the relaunching circulator requires the optional “GI” module code 00264034
6.6.3
PM Module phase protection
The PM module detects the correct sequence of the 3-phases (L1, L2, and L3) power supply. The 3-phases power supply must be
connected respecting the correct sequence of the phases so as to ensure the right direction of rotation at the compressor start-up
and during operation. When the PM module acts for lack of phase, the controller will receive a signal to interrupt it from the
power supply.
6.6.4
Plant management optional module terminal block CODE 00264034
Where the plant management kit (optional) is present, a third controller is located inside the electric panel, which acts as I/O
resource expansion module. With this controller, it is therefore possible to increase the number of logics handled by the main
controller; in particular these logics are used to manage the plant system and are reported below. The functions described below
can be activated by the on-board unit controller that is located on the unit’s front panel.
For the configuration of the functionalities, please check the control manual supplied with the unit.
