Note:
If "N" is entered, all rectifiers/PCUs will be turned on
simultaneously after the transfer back to AC power.
4. The system responds with...
AC Fail/Transfer Input= current info
AC Fail/Transfer Input=
5. Type the number of the binary channel connected to the
AC fail/transfer signal, then press
ENTER
. If the binary
channel displayed is the correct number, press the
ENTER
key to proceed. This binary input monitors the status of
the commercial AC line or the power transfer signal, and
shuts down the rectifiers/PCUs when the AC fails, or
when the transfer switch has been operated. The binary
input alarm condition is determined when the binary
channel is configured.
6. The system responds with...
Input Type (Fail or Transfer):
7. The system recognizes both a momentary type signal
from a transfer switch, and a status type signal from an
AC Fail sense circuit. Type
FAIL
if the AC Fail/Transfer
Input monitors a steady state signal, and
TRANSFER
if it
monitors a momentary signal. Then press
ENTER
.
8. The system responds with...
Standby Sequencer on (Y or N):
9. Type
Y
if it is desired to enable sequencing of standby
rectifiers/PCUs. Type
N
if sequencing of standby
rectifiers/PCUs is not desired. Then press
ENTER
.
Note:
If "N" is entered, all standby rectifiers/PCUs will be
turned on simultaneously when the transfer to
standby power is complete.
10. The system responds with...
Standby On/Proper Operate Input= current
info
Standby On/Proper Operate Input=
11. Type the number of the binary channel connected to the
standby on/proper operate signal, then press
ENTER
. If
the binary channel displayed is the correct number, press
the
ENTER
key to proceed. This binary input activates the
standby sequencer after a commercial AC failure occurs.
The binary input alarm condition is determined when the
binary channel is configured. This signal monitors the
status of the standby power source, and indicates that
the standby power source is delivering power to the load.
12. The system responds with...
Standby Start Delay: current info
Standby Start Delay:
13. Type the desired standby sequential start time delay
(15-1200 seconds) which will occur after the standby
on/proper operate circuit is activated, then press
ENTER
.
If the start delay time displayed is correct, press the
ENTER
key to proceed. The rectifiers/PCUs are not
sequenced on until after this delay time is up.
Note:
There is a processing time delay of up to 18 seconds
from the time the AC fail signal is asserted to the
time the sequencing routine shuts off the
rectifiers/PCUs.
14. The system responds with...
Sequencer Failsafe time: current info
Sequencer Failsafe time:
15. Type the desired value (60-9999 seconds, 0=disabled) for
the Sequencer Failsafe Timer feature. Then press
ENTER
.
This feature aborts sequencer operation when an
external monitoring device controlling sequencer
operation fails. The Sequencer Failsafe Time value should
be greater than the Standby Start Delay value, or set to
zero (0) to disable the feature.
The timer starts when the system detects an AC failure or
loss of Standby On/Proper Operate signal. If the timer
expires before a signal is received, indicating that the
commercial AC is restored or load was transferred to the
standby power source, the following occur: The
sequencer is disabled, an entry is made in the event log,
the sequencer variables are reset, and all rectifiers/PCUs
are turned on. If a signal is received before the timer
expires, the timer is deactivated and reset. When the
sequencer is disabled, the Set Sequence command must
be re-issued to re-enable sequencer operation.
Note:
An alarm report indicating that sequencer has
aborted can be generated by configuring the alarm
type and the program line of an LED or relay channel
as follows: Rxx=E1, Lxx=E1.
16. If "Fail" was entered above in Step 10), the system
responds with...
AC Restoration Qualification time:
current info
AC Restoration Qualification time:
17. Type the desired value (0-9999 seconds, 0=disabled) for
the AC Restoration Qualification Timer feature. Then
press
ENTER
. This feature is only available when the
INPUT TYPE attribute of the sequencer is configured as a
FAIL type, and not as a TRANSFER type. This feature
allows the sequencer to turn all rectifiers/PCUs off and
start the sequence re-start operation at a specific time
interval from when commercial AC is restored.
