BULLETIN 1336
FAULT RESET/AUTO RESTART
APPLICATION NOTE #7
January 2, 1997
PURPOSE
The purpose of this document is to provide guidelines for
wiring and control schemes for the Bulletin 1336 AC Drive.
This document is to be used as a suggestion only. Users
must
ensure that installations meet applicable codes and are
suitable for the existing conditions.
The Bulletin 1336 User Manual should be used as a reference
to ensure that proper wire selection,routing,and fusing
guidelines are followed.
WHAT THIS NOTE
CONTAINS
for
The Bulletin 1336 drive can be configured to automatically
reset a fault and then restart the drive. This is useful
unmanned areas that may have frequent power outages.
The start/stop control inputs must be TWO-WIRE control to
allow the drive logic to perform the auto restart function.
This note contains diagrams and parameter programming used
to implement the auto restart function.
INTENDED
AUDIENCE
This application note is intended to be used by personnel
familiar with the hardware components and programming
procedure necessary to operate the Bulletin 1336/1336VT.
WHERE IT
IS USED
The diagrams, parameter settings, and auxiliary hardware
used in this application note are designed to address
specific issues in many different applications. Some
by the Users may be necessary to apply the concepts
document to a specific application.

DESCRIPTION
The 1336 requires that a 2-wire start/stop circuit be used
with the auto restart function. The start command must
remain "logically true" for the auto restart to function
properly. One of the three Logic Interface cards (MOD-L1,L2
or L3) must be installed on the drive.
The fault reset function is enabled by setting Parameter 85
(Restart Tries) to a value between 1 and 9. This setting
then becomes the "counter" value for the Restart attempts.
Parameter 14 (Auto Restart) and Parameter 40 (Power Fault)
must also be set to a value of 1.
When a fault occurs,the drive software starts two timers -
A
20 second restart time delay and a 4 minute restart period.
The 20 second timer is used as a delay between restart
attempts. The 4 minute timer is used as a "watchdog" to
ensure that the drive does not remain in the "restart" mode
for more than 4 minutes.
The restart
Tries until
the Retries
F13-F18 and
process will continue for the number of Restart
the 4 minute time period expires. Once expired,
Exceeded (F33) fault will be set. Fault codes
F33 require the drive to be manually reset.
The drive may be reset by one of 3 methods.
1. Cycle the input power to the drive and allow the drive
to
completely discharge the stored energy in the capacitor
bank.
2. Set parameter 39 to a value of 1. This will allow
the fault to be cleared by cycling the STOP input, TB2
terminal 20, false then true.
3. If the 1336-MOD-G2 Serial Interface is used, a BTW to
parameter 51 (Clear Fault) will also clear the fault.
The
Serial Interface will not allow F10 (Communication Loss)
fault to be cleared.
Refer to figure 1 for diagram with 115vac interface.
Refer to figure 2 for diagram with TTL interface.
