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
Operating current (NO): The discrete input is enabled by energizing it.
This does not provide wire break monitoring!
Closed circuit current (NC):
The discrete input is enabled by de-energizing it.
This may provide wire break monitoring.
Example: Discrete inputs 1 through 4 (same procedure for inputs 5 to 16)
Parameter 225
Dig.input 1234
function EEEE
Function of the discrete alarm inputs 1 to 4 E/D
The discrete inputs may be operated by an operating current contact or a closed cir-
cuit current contact. The closed circuit current input may be used to monitor for a
wire break. A positive or negative voltage difference 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 226
Dig.input 1234
delay 0000
Delay time of the discrete alarm inputs 1 to 4 0 to 9
A delay time in stages can be assigned to each alarm input. The individual stages
are listed below. The discrete input must be present 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 227
Delayed by 1234
eng.speed YYYY
Delayed by firing speed of the discrete alarm inputs 1 to 4 Y/N
If the discrete input used as an alarm input is only to be monitored when the engine
is running ("firing speed reached") is specified here.
Y ................... After engine monitoring has been enabled the discrete input is moni-
tored.
N ................... The discrete input is always monitored.
