Alarm Inputs
Discrete input 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Name 1 2 3 4 5 6 7 8 9 A B C D E F G
Terminal 34 35 36 61 62 63 64 65 66 67 68 69 70 71 72 73
Function A A A A A/C A/C A/C A A A/C A A A/C A A A
A..Alarm input; A/C..Alarm or control input (dependent on the configuration)
NOTE
Normally Open (N.O.): Energizing the discrete input will enable the relay.
This does not provide wire break monitoring!
Normally Closed (N.C.):
De-energizing the discrete input will enable the relay.
This may provide wire break monitoring.
Example: Discrete inputs 1 through 4 (use the same procedure for inputs 5 to 16)
Parameter 199
Dig.input 1234
function EEEE
Function of the discrete alarm inputs 1 to 4 E/D
The discrete inputs may be operated by a normally open contact or a normally
closed contact. The normally closed contact input may be used to monitor for a
wire break. A positive or negative voltage polarity may be utilized.
D ................... The discrete input is normally de-energized and analyzed as
"enabled" by energizing the input (N.O.; D = normally d
e-energized).
E ................... The discrete input is normally energized and analyzed as "enabled"
by de-energizing the input (N.C.; E = normally e
nergized).
Parameter 200
Dig.input 1234
delay 0000
Delay time of the discrete alarm inputs 1 to 4 0 to 9
A delay time can be assigned to each alarm input. The delay times are configured
as stages. The individual stages are listed below. The discrete input must be ener-
gized/de-energized, depending on how it is configured, without interruption
throughout the delay time in order to be "enabled".
Delay stage Delay stage
0 100 ms
1 200 ms
2 500 ms
3 1 s
4 2 s
5 5 s
6 10 s
7 20 s
8 50 s
9 100 s
Table 3-9: Discrete alarm inputs - delay stages
Parameter 201
Delayed by 1234
eng.speed YYYY
Delayed by firing speed of the discrete alarm inputs 1 to 4 Y/N
It is possible to configure the GCP to ignore discrete inputs until the engine has
achieved firing speed. This parameter defines if the discrete input, which is being
used as an alarm input, is only to be monitored after the engine is running ("firing
speed reached").
Y ................... The discrete input is only monitored after the engine firing speed has
been achieved and monitoring of the engine protections have been
enabled.
N ................... The discrete input is always monitored.
