INTKL OPEN
: Indicates the EXTERNAL
INTERLOCK connections are in the open position.
This also indicates opening of internal power supply
interlocks.
OVERVOLT:
Indicates the overvoltage protection
circuitry has caused the power supply to turn off.
Overvoltage protection is internally set to 110% of
the rated output voltage.
OVERCURR
: Indicates the output current has
exceeded the programmed current trip level when the
AOL (Adjustable Overload Trip) or the OL
(Overload Trip) options are installed.
OVERPOWER:
Indicates the output power has
exceeded the internally set level or the remote
programmed level if the optional circuitry is installed.
ARC
: Indicates that an arc has occurred within the
previous one second or that the ARC COUNT/TRIP
has shutdown the power supply.
RGLT ERR:
Indicates a failure in the voltage,
current or power regulation circuitry. This fault
usually occurs when there is a lack of output power to
maintain regulation.
The options available are listed in Table 1.1. See Section
5 for more information on these options along with
operating and set-up instructions. With few exceptions,
these options and modifications can be retrofitted to your
power supply at the factory in a short time. For price and
retrofit arrangements, contact the Spellman Sales
Department.
