C H A P. 1 - I n t r o d u c t i o n SC 600 PLUS CHAPTER 1: INTRODUCTION G E N E R A L F E AT U R E S 1.1 The SC600 PLUS system allows users to control the machine room of a refrigeration plant in which there is more than one compressor. It guarantees uniform operation and proper distribution of operating times among individual machines.
C H A P. 2 - I n s t a l l a t i o n SC 600 PLUS CHAPTER 2: INSTALLATION IMPORTANT GENERAL INFORMATION FOR THE USER 2.1 1. Install the device in places where the protection rating is observed and try not to damage the box when drilling holes for wire/pipe seats. 2. Do not use multi-polar cables in which there are wires connected to inductive/power loads or signalling wires (e.g. probes and digital inputs). 3.

C H A P. 3 - F u n c t i o n a l i t y SC 600 PLUS Effect all electrical connections as illustrated in the diagram for the corresponding model (see relative table in APPENDICES). To effect correct electrical connection and maintain the protection rating, use lead grippers and/or duct grippers to ensure a good seal. Route the wiring inside the unit in as tidy a fashion as possible: be especially careful to keep power wires away from signal wires. Use clips to hold wires in place.

C A P. 5 - P a r a m e t e r s p r o g r a m m i n g SC 600 PLUS CHAPTER 5: PARAMETER PROGRAMMING PLUS SC 600 CONTROL PANEL 5.1 The Control Console is used to program and display the parameters. The Console can be installed directly in the machine room (e.g. power cabinet front) or in any other position where visual control of plant operation might be useful. The Control Console features CONTROL KEYS, INFO/WARNING ICONS and a DISPLAY which is used to program and view all the main parameters.

SC 600 PLUS C A P. 6 - Description of operation CHAPTER 6: DESCRIPTION OF OPERATION 6.1 OPERATION The SC 600 PLUS system manages 4 compressors and 4 fans, or 3 compressors each with a separation and 3 fans, according to the parameter settings made during programming. Fans can be disabled.
C A P. 7 - D i a g n o s t i c s SC 600 PLUS OPERATION “WITH ROTATION” 6.5 Each activation request is followed by a fixed 10-second delay (indicated by the flashing LED of the corresponding compressor) and then activation of the compressor with the shortest working time; subsequently, compressors with working times longer than that of the previous one are switched on.
SC 600 PLUS ALARM CODE C A P. 7 - D i a g n o s t i c s PROBABLE CAUSE SOLUTION E1 Faulty high pressure sensor. E3 EEPROM ALARM An error in the EEPROM memory has been detected (all outputs except alarm output are deactivated). Master/slave software incompatibility error. One or more compressors has reached the number of working hours at which maintenance is required. Clock battery flat. Unit in manual pre-alarm. • Check the sensor is working properly.
C A P. 7 - D i a g n o s t i c s SC 600 PLUS ALARMS DATABASE 7.2 The SC600 PLUS system can save up to 40 alarm events.To display the recorded alarm codes press the ALARM MUTE key for at least 2.5 seconds. Sector n. 22 of the LCD display (see section 5.2) shows the dominant (highest priority) error code at the time of saving. Sector n. 23 indicates the data saving date (if alarm refers to current day the time is shown).
