Key
Inputs
▲ If input is On, the change to the next phase on the right is made
▼ If input is Off, the change to the next phase on the right is made
XXX▲ If input is On, the change to phase XXX is made
XXX▼ If input is Off, the change to phase XXX is made
↑
If the input is On at the end of the phase, the change to the next phase on the right is
made
Input must be Off, otherwise home run
Input must be On, otherwise home run
Input must be Off, otherwise lockout
Input must be On, otherwise lockout
Input must be Off, otherwise shutdown
Input must be On, otherwise shutdown
Input must be Off, otherwise start prevention (phase STV)
Input must be On, otherwise start prevention (phase STV)
Input monitored to see if it is OFF, error response only evaluated during the subsequent
phase
Input monitored to see if it is ON, error response only evaluated during the subsequent
phase
Outputs
Output Off
Output On
Supervision of current fan
speed
▲
If the speed is higher than the lower/upper limit, the change to the next phase on the right
is made
▼
If the speed is lower than lower/upper limit, the change to the next phase on the right is
made
Speed not permitted, home run if violation exceeds the tolerated time
Speed not permitted, lockout if violation exceeds the tolerated time
Lower/upper speed limit
Required speed
Response to errors
In case of deviation: Forced prepurging (can be parameterized)
In case of deviation: Error counter No flame end of TSA is incremented.
If the counter shows the same value as the Max StartAttemps TSA [3633.1] repetition
counter, the lockout position is adopted.
Error counter is reset in operating phase
In case of deviation: Error counter GP errors during TSA is incremented.
If the counter shows the same value as the Max StartAttemps TSA [3633.1] repetition
counter, start prevention is applied for two hours.
Error counter is reset in operating phase TI.
V
The duration of the phase is extended in accordance with how long the deviation persists.
In case of deviation: Error counter Air supply is incremented. Lockout if counter reads 2.
Error counter is reset after shutdown of controller
Subsequential phase
* Next phase depending on parameterization
