Operating Instructions (Cont.)
Operation
SPECTRON electronics operation is fully automatic.
Accidental discharge of the unit battery prior to
energization is prevented by an AC lockout circuit.
The unit's green Operating Status LED, located on
the Spectron display panel, illuminates to indicate
the presence of AC power. The unit's red Service
Alert LED will blink after application of AC power if the
battery connection is not completed. During normal
operation, the unit's charging circuit maintains the
battery at full capacity and the Spectron Controller
constantly monitors charger performance. Should
the terminal voltage vary from design parameter
values, the unit's red Service Alert LED will blink ,
indicating a malfunction of the battery or charger.
Upon interruption of normal AC power, or brownout
condition, the Spectron Controller automatically
switches the emergency lighting load to the battery.
Emergency power will be provided for a minimum of
90 minutes. During emergency operation, the battery
is protected from deep discharge by a low voltage
battery disconnect circuit. Upon return of normal AC
power, a 15 minute retransfer delay holds the unit in
emergency operation mode allowing utility voltage to
stabilize prior to reconnection. The charger will then
begin a recharge cycle. A temperature compensated
float type charger is provided in LT models. This
charger is designed to adjust charging voltage with
changes in ambient temperature to maximize the life
and performance of the unit's pure-lead type batteries.
All other Liteforms Series exit signs utilize constant
current type chargers which require no temperature
compensation to maintain the unit's Nickel-Cadmium
batteries. All chargers will bring the unit battery to
full capacity within acceptable U.L. time standards.
The Spectron Controller automatically initiates a one
minute discharge/diagnostic test every 28 days ±
3.5 hours and a 30-minute discharge/diagnostic test
every 6 months ± 1 day. These tests exercise the
unit’s battery to optimize its capacity and allows the
SPECTRON Controller to analyze emergency operation
performance. Any malfunction of the unit’s transfer
circuit or emergency lamps will cause the red Service
Alert LED on the unit's display panel to blink. During
normal operation, all red Service Alert LED blinking
indications of unit malfunction remain latched until
corrected and retested. A manual test switch allows a
user programmable 1, 5, 30 or 60-minute diagnostic/
discharge test at any time. During all automatic and
user initiated self-tests, the unit's green Operating
Status LED will blink to indicate a diagnostic cycle in
process.
