Parameter Group G1.2: Input Signals
P1.2.1
DIN1 Function
P1.2.2
Interlock Timeout
P1.2.3
Delay Time
8-4
Range: 0 – 3
Default: 0 (Start)
DIN1 Function
This parameter determines the function of digital input DIN1.
0 Start – standard start
1 Interlocked Start – To use this, a relay output, RO1 – RO8, needs to be
programmed for selections 27 “Open Damper,” and a digital input DIN2 to
DIN6 must be programmed for selection 3 “RunEn/INTLK.” 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 contact closure to the programmed digital input, the
HVX9000 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, an “IntlkTimeExpired RestartDrive” message is
displayed 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 HVX9000 starts.
Note: Selections 1 – 3 will only function properly with BAS selected for the
“Start Source”.
Range: 1 – 32,500
Default: 5
Units: Seconds
Intlk Timeout
The timeout time used for an Interlocked Time Start, after which the start
sequence must be restarted if no acknowledgement contact is received. See
DIN1 Function. This parameter is also used for the Panel Damper Function
“Interlock Time Start,” P2.5.
Range: 1 – 32,500
Default: 5
Units: Seconds
Delay Time
The delay time following a Delay Start, after which the HVX9000 will be
started. See DIN1 Function. This parameter is also used for the Panel Damper
Function “Delay Start”, P2.5.
