4 1 - SAFETY CONSIDERATIONS 1.1 - General Installation, start-up and servicing of equipment can be hazard- ous if factors particular to the installation are not considered: operating pressures, electrical components, voltages and the installation site itself (elevated plinths, rooftops and built-up structures).
5 2 - GENERAL DESCRIPTION 2.1 - General PRO-DIALOG Plus is a system for controlling units which use reciprocating compressors*: • Single or dual circuit • Air or water-cooled condensers • Non-reversible heat pumps • Split systems * At present only air-cooled models are available.
6 3 - HARDWARE DESCRIPTION 3.1 - General Control board The various control components are arranged in modules within the control cabinet: • Control module: This comprises the basic board, the user interface, the EXV control board and option boards, as well as the customer’s terminal block.
7 3.2.7 - Light emitting diodes on boards All boards continuously check and indicate the proper operation of their electronic circuits. A light emitting diode (LED) lights on each board when it is operating properly. Red LED • The MAIN red LED flashes at about 2 second intervals to show that the module is working properly.
8 3.3.3 - The evaporator pumps The controller can regulate one or two evaporator pumps, with automatic changeover between the two pumps. 3.3.4 - The condenser pump In appropriate cases the controller can regulate a condenser pump (for water -cooled units or air -cooled units with heat reclaim option).
