Table 66. HVAC parameters (Cont.).
P8.1 - Damper (*DM1 PRO).
P8.1.1
ab
Damper start
ID 483
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Start - standard start.
1 = Interlocked start: To use this, a relay output, RO1/RO2, needs to be programmed for selections 29 “Damper Control” and a digital
input function must be programmed for selection “RunEnable”. The relay output is used to energize an element of the driven system,
such as a damper, seal water solenoid, or a pre-lube pump. Upon a return acknowledgement of contact closure to the programmed
digital input, the frequency converter will start.
2 = Interlock time start: This functions the same as the interlocked start, except that if the return acknowledgement contact is not
received within the interlock timeout, a “prevent-up start” fault is displayed in keypad and the start sequence will need to be
restarted.
3 = Delay start: This start is similar to the interlocked start, except that a return contact is not used. After the “Delay Time” following
the relay output closure, the frequency converter starts.
Description:
This parameter determines the function of the damper.
P8.1.2
ab
Damper time out
ID 484
Minimum value:
1 s
Maximum value:
32,500 s
Default value:
5 s
Description:
The time out time used for an interlocked time start, after which the start sequence must be restarted if no acknowledgement contact
is received.
P8.1.3
ab
Damper delay
ID 485
Minimum value:
1 s
Maximum value:
32,500 s
Default value:
5 s
Description:
The delay time following a delay start, after which the frequency converter will be started.
