6. CEC7 CONTROL UNIT INPUTS AND OUTPUTS
The CEC7 control unit's digital inputs - ENT1, ENT2 and ENT3- have a debounce
time associated (Times table, parameters 22 to 24) which requires that the value
of the input is stable over a time interval. Also, the CEC7 control unit's inputs can
be congured to be active with contact closed to earth or be inactive with contact
closed to earth (Regulations table parameters 11 to 14).
The status of the CEC7 control unit's inputs and outputs can be monitored from
the Main menuà1.Inputs/Outputs. From that position, a screen displays the
status of the control unit's digital inputs and outputs:
* I N P U T S / O U T P U T S *
3 2 1 0 9 8 7 6 5 4 3 2 1
I N : 3 2 1 P
O U T : B g r
Detection of an active input is indicated by the following characters:
• IN 1. P: Emergency stop (PEM).
• IN 2. 1: Programmable input 1.
• IN 3. 2: Programmable input 2.
• IN 4. 3: Programmable input 3.
Detection of an active output is indicated by the following characters:
• OUT 1. r: Network contactor (CRC, CRNA, CRNC).
• OUT 2. g: Genset contactor (CGC, CGNA, CGNC).
• OUT 3. B: Free voltage contact genset start (BTNA, BTA).
By pressing the up or down scroll keys it is possible to display the analogue
inputs of the generator set.
