T-5800-3/T-5800-4 Technical Bulletin 11
B. Receiver-Controllers
Having Fan “F”
Connection Capped
(System ON 100% of the
Time)
When the system becomes
stable, stop the system and
disconnect the P/PI jumper.
Allow enough time to pass
until the controlled variable
deviates from the set point.
Restart the system,
reconnect the P/PI jumper,
and observe to see how well
the system comes into
control. If the system
response is not as desired,
repeat the Integral Time
Adjustment procedure
above.
Note: If the system is
shut down (power failure,
cleaning, repair, etc.), the
P/PI jumper must be
disconnected and left
vented for a period of time
equal to the integral time
dial setting. Start up the
system and reconnect the
P/PI jumper when the
system becomes stable.
T-5800-100 Time Delay (When
Fan “F” Connection is Used)
After system startup, if the
system response is too slow, the
integral control function will act
on the signal before the
proportional control function
settles out. To eliminate this
problem, a T-5800-100 Time
Delay (ordered separately) must
be added to the fan “F”
connection (see Fig 19). This
device will delay the pressure
increase to the fan “F”
connection of the receiver-
controller, allowing more time for
the system to achieve stable
proportional control before the
integral control function is
initiated.
