Parameter
220
Delay
Limit 1/2 000s
Analog input, 0/4 to 20 mA: delay (limit 1 + 2)
0 to 600 s
The analog input monitoring threshold limit must be exceeded, without interrup-
tion, for the time period configured here before an alarm is issued (this delay time
applies to both limit values).

Monitoring for
----------------
Analog input, 0/4 to 20 mA: monitoring for
high limit mon./low limit mon.
The analog input is monitored in different manners:
high limit mon.
.... The value must exceed the configured limit.
low limit mon.
The value must fall below the configured limit.

Analog input: measuring range monitoring
This message appears when positive or negative deviation from the measuring
range occurs. The control assesses a fault condition depending on the values speci-
fied below.
NOTE
The control assesses that a wire break has occurred when the following values are measured for the
listed analog input types. When a wire break has been assessed by the control, the threshold limit
monitoring for the analog input is deactivated.

Delayed Monitoring of the Analog Inputs
Parameter
223
An.input 1234
Superv.del. YYYY
Analog input: delayed monitoring 1 through 4
Y/N
The user may enable analog inputs 1 through 4 to be constantly monitored or only
monitored when the engine is running ("firing speed reached").
Y
................... Monitoring of the analog input is delayed by the time configured in
Parameter 239 (green "Monitoring" LED is illuminated).
N
................... The analog input is always monitored.
Parameter

An.input 5678
Superv.del. NNNN
Analog input: delayed monitoring 5 to 8
Y/N
The user may enable analog inputs 5 through 8 to be constantly monitored or only
monitored when the engine is running ("firing speed reached").
Y
................... Monitoring of the analog input is delayed by the time configured in
Parameter 239 (green "Monitoring" LED is illuminated).
N
................... The analog input is always monitored.
