Type summary and ordering information (cont’d)
Note on parameterization:
Use the display and operating unit (display) AZL2 to ensure that the exact value of the required time
is always set as multiples of increments of 0.147 seconds. When parameterizing minimum or
maximum times, a potential tolerance of ±7% must be taken into consideration.
The following applies to minimum values: At least one value which is 7% greater must
be parameterized.
The following applies to maximum values: At least one value which is 7% smaller must
be parameterized.
Example 1:
Calculation:
The flame signal flame-out response time tab must not be set above 5 seconds
(5 seconds – 1 second) – 7% = 3.65 seconds
Value to be parameterized
(parameter 217.01): Must be the same as or smaller than the calculated value (e.g., 3.528 seconds)
Example 2:
Calculation:
The flame signal flame-on response time tan must be set to at least 5 seconds
(5 seconds – 0.3 seconds) + 7% = 5.05 seconds
Value to be parameterized
(parameter 217.00): Must be the same as or greater than the calculated value (e.g., 5.145 seconds)
