Page 4: Monitoring And Regulation
1 - MONITORING AND REGULATION 1.1 Controller Each air heater is managed by the controller. In addition to its control functions, it also monitors and detects any faults with the air handling unit. IMPORTANT: To avoid any problems, the password must be known only by qualified personnel. 1.2 The pLDPRO terminal The terminal is supplied equipped with an LCD screen (8 lines x 22 characters) with six control keys. -

2 - CONFIGURING THE CONTROLLER The controller and display must be configured before the unit is commissioned. 2.1 Configuring with master EC Mono Boxes only: The value of the display's factory-set address is '32'. It is pointless to only change it in the master EC Mono Box. If the nn field is set to '0', the terminal will use the Point-to-Point Protocol (not the pLAN) to communicate with the controller and the “I/O Board address: xx”... -

The Slave EC Box/display connection no. 1 has been made, if there are other slave boxes to be configured, repeat point d) by increasing the I/O Board address by 1 each time (e.g. for the 2nd slave: I/O Board address 3; for the 3rd slave: I/O Board address 4, etc.). -
Page 11: Addressing The Plan
3.2 Addressing the pLAN There is a range of 32 possible addresses (binary logic). As a result, a total of 32 controllers and terminals can be connected over the pLAN network. The pLAN network will not work if the same address is shared by two components! pLDPRO display Address: 32... - Page 12 "Prg" key Menu □14.Access level □16.Versions □1.Setpoints □2.Machine status □4.Machine parameters To switch to another menu, press the or keys to scroll through the available menus.
