3.f.5 Communication Parameters (P4.5):
3.f.5.1 Load Valve Control Source (P4.5.1):
This parameter determines which source controls the load valve of CCS 3000. If this parameter is selected as other than
“Remote”, the related input may be used as digital alarm input. There are 3 sources in CCS 3000:
• Sensor: In this mode, CCS 3000 controls the load valve with the pressure sensor.
• Remote: In this mode, CCS 3000 controls the load valve with Remote Valve Control (digital input: IN5). This input
may be selected as falling-edge trigger or rising-edge trigger.
When the input contact type is NC (normally closed), the load valve is energized during the closed-circuit to
open-circuit transition (falling-edge). The load valve is deenergized when it is closed circuit.
When the input contact type is NO (normally open), the load valve is energized during open-circuit to closed
Circuit (rising edge). The load valve is deenergized when it is open-circuit.
In this mode, “P3.2 Pressure Unload” and “P3.4 Pressure to Load” parameters have no effect on air pressure control.
!Note: Please make sure that IN5 type is correct in “P5.1 Input Contact Type ” heading while working in this mode.
• MODBUS: In this mode, CCS3000 controls the load valve over communication. In this mode, “P3.2 Pressure
Unload” and “P3.4 Pressure to Load” parameters have no effect on air pressure control.
3.f.5.2 Start/Stop Control Source (P4.5.2):
This parameter determines which source controls start/stop. If this parameter is selected as other than “Remote”, the related
input may be used as digital alarm input. There are 3 sources in CCS 3000:
• Panel: In this mode, and buttons on CCS3000 panel are used for starting and stopping.
• Remote: In this mode, CCS3000 start/stop is handled by Remote Start/Stop digital input (DIN7). This input may be
selected as falling-edge trigger or rising-edge trigger.
When the input contact type is NC (normally closed), the compressor is started during closed-circuit to open-
circuit transition (falling edge). The compressor is stopped when it is closed-circuit.
When the input contact type is NO, the compressor is started during open-circuit to closed-circuit transition
(rising edge). The compressor is stopped when it is open-circuit.
In this mode, button on the panel has no effect. When button is pressed, the compressor is stopped when
“P3.5 To Stop Delay” timer expires.
!note: Please make sure that the contact type for IN6 is selected correctly in “P5.1 Input Contact Type ”
heading.
• MODBUS : In this mode, CCS3000 makes start/stop over communication.
