Diagnostic Indicator Functions:
Table 1 lists the diagnostic functions of the
57000 series panels.
Module Diagnostics:
Each module contains two Green LEDs. When
illuminated, they indicate that the module is properly seated, power for that
phase is present, and the protection fuse for that module is intact.
For the
57000-M3
, one of the two LEDs indicates proper functioning of the primary
surge protection circuitry, while the other LED monitors the alternate (back-up)
surge protection circuitry. Alternate surge protection circuitry is located in a
different module than the primary protection for any phase. Therefore, if one
module fails or is removed, all phases retain their surge protection (at a
reduced level).
The 57000-M3S
modules have L-N & L-G protection rather than primary and
alternate (back-up) protection. Each module provides L-N & L-G protection for
the same phase.
Modules should be replaced as soon as possible after a failure is noted (unlit
Green LED). Absence of illuminated LEDs indicates either a loss of power or a
blown fuse due to excessive transients, such as due to a direct lightning strike.
When this occurs, refer to the Module LED/Fuse Correspondence Chart
(located inside panel door) for the list of the Green LED indicators and their
designated fuses.
Fault Indication:
A flashing Red warning LED, in addition to an audible beep
tone, indicates loss of power to the modules. This can be due to the absence
of main phase power, or a blown fuse caused by module failure due to
transient over-stress (a condition which causes the Fault Indication). It also
transmits the occurrence to a remote indicator (an accessory item) via an
optically isolated Class II wire pair.
NOTE: (For Delta panels only). If the Red LED flashes and the audible
tone is activated, but all Green module LEDs are illuminated, the cause is
an open phase voltage rather than an open fuse.
Beep Disable Switch:
When a fault has been indicated and noted by
authorized personnel, the audible beep tone may be disabled by momentarily
pressing the beep disable switch. The Red warning LED will continue to flash.
When the malfunctioning fuse and module have been replaced, the beep
disable switch should be pressed again in order to re-enable the audible beep
tone.
Battery Function:
In the unlikely event that more than one fuse has blown, a
9-volt alkaline battery is utilized to power the diagnostic circuitry so as to alert
the user that there is a problem. When this occurs, the flashing Red warning

PARA INSTALAR:
1.
ADVERTENCIA:
PARA EVITAR DESCARGA ELÉCTRICA, FUEGO, O
MUERTE,
INTERRUMPA EL PASO DE ENERGÍA
MEDIANTE EL
INTERRUPTOR DE CIRCUITO O FUSIBLE. ¡ASEGÚRESE DE QUE EL
CIRCUITO NO ESTÉ ENERGIZADO ANTES DE INICIAR LA
INSTALACIÓN!
2. Identifique el aparato o la carga a proteger:
Para minimizar los efectos
de resistencia y de inductancia en la longitud de conexión, ubique la
unidad DPS tan cerca como sea posible al panel eléctrico que da servicio a
la carga a proteger.
