VersiStart p III
A shorted SCR or a short within the bypass contactor will trip the starter on ‘Lx-Tx
shorted’. If PowerThrough is enabled, the trip can be reset and subsequent starts
will use PowerThrough two-phase control; however not all features will be available.
The trip LED will flash and the display will indicate ‘2 Phase - Damaged SCR'.
CAUTION
PowerThrough uses a two-phase soft start technology and additional care
is required when sizing circuit breakers and protection. Contact your local
supplier for assistance.
CAUTION
The starter will trip on Lx-Tx Shorted on the first start attempt after control
power is applied. PowerThrough will not operate if control power is cycled
between starts.
PowerThrough operation does not support Adaptive Control soft starting or
soft stopping. In PowerThrough, the VersiStart p III will automatically select
constant current soft starting and timed voltage ramp soft stopping. If
PowerThrough is enabled, parameters 2C and 2D must be set
appropriately.
9.5 Emergency Mode
Emergency mode allows the VersiStart p III to run the motor and ignore trip
conditions.
Emergency mode is controlled via a programmable input (input A 13, 14 or input B
13, 15) and parameter 7A
Input A Function
/7E
Input B Function
must be set to
'Emergency Mode'. A closed circuit across 13, 14 activates emergency mode.
When the VersiStart p III receives a start command, it will continue to run until a
stop command is received, ignoring all trips and warnings.
Emergency mode can be used in conjunction with any command source.
NOTE
Although emergency mode operation satisfies the functionality
requirements of Fire Mode, Peter Electronic does not recommend its use in
situations that require testing and/or compliance with specific standards as
it is not certified.
CAUTION
Continued use of emergency mode is not recommended. Emergency mode
may compromise the starter and/or motor life as all protections and trips are
disabled.
Using the starter in emergency mode will void the product warranty.
