FX70 Supervisory Controller Installation Instructions

Operation
Apply Power
The FX70 does not include an on/off switch. To apply
power, you simply energize the AC circuit (90–263
VAC) wired to the attached LP-FXPM263-0 power
supply module. If remote I/O modules are wired to the
unit, they are also typically powered by the controller as
well.
If powering the FX70 (only) with a LP-FXPMxx-0 (Wall
Mount AC Adapter), simply plug the AC adapter into a
nearby wall outlet.
Check the Status LED
When power is applied, the front cover STATUS LED
lights green. This indicates that the system is OK and
that power is applied. The STATUS LED may be
blinking until the QNX OS has finished loading and the
Niagara platform daemon is running.
Once this boot sequence has finished, the STATUS
LED should remain lit (steady), and the BEAT LED
should start blinking, at a typical rate of 1 Hz. Typically,
this is about 30 seconds after power is applied.
If after applying power, the STATUS LED goes out, or if
the BEAT LED comes on (steady) and stays lit longer
than 2 minutes, contact your technical support
representative for assistance. See also
Backup Batteries
The FX70 has two different backup batteries:
•
An on-board NiMH battery pack, and
•
An optional external, sealed lead-acid,
rechargeable Backup Battery (or batteries).
For continuous system operation during loss of primary
power (to the LP-FXPM263-0 module powering the
unit), unless power loss is only a few seconds, both
batteries should be installed. Station alarms are
generated if either battery is uncharged or unable to
hold a sufficient charge, as well as whenever primary
power is lost. You should always investigate any alarm
related to backup batteries.
NiMH Battery Pack
A custom 10-cell NiMH battery pack is inside the
controller, mounted atop the shield, and is secured by a
metal bracket and two kep nuts. This battery allows the
controller to continue station operation (only) through
very short power bumps, meaning a few seconds in
duration. If a longer outage, the NiMH battery provides
enough run time for the unit to backup data and then
shutdown. Typically, this process takes about 1 minute.
Shutdown occurs automatically, after data is backed up
to on-board flash memory.
Upon startup (boot), a test of the NiMH battery is
performed. A system alarm is generated if the NiMH
battery voltage level is found to be bad. A charge is
also initiated upon startup, which lasts from 3 hours
minimum, and can range up to 18 hours if the battery is
completely discharged. During this NiMH battery
charge period, neither the NiMH battery or the external
Backup Battery is tested. After the startup NiMH charge
period, a periodic test of both batteries occurs, and the
appropriate battery alarm is generated if either battery
is found to be bad.
Note:
If the last NiMH battery test is bad, the
controller performs an immediate shutdown upon loss
of primary power, backing up data and powering off
(including attached readers, and expansion modules).
Note:
A NiMH battery characteristic loses charge if
not left in charge mode (trickle charge). Leaving the
battery unconnected (or powered off in the unit) causes
the battery to fully discharge in a matter of weeks. Note
that a new controller ships from the factory with a
completely discharged battery. Therefore, allow at least
18 hours for the battery to charge if it has not been in a
powered unit.
You should replace the NiMH battery pack
approximately every 3 years, or more often if the unit is
in a high temperature environment. For more
information on the use and replacement of the battery,
refer to the

CAUTION: Risk of Property Damage
Do not apply power to the system before
checking all wiring connections. Short
circuited or improperly connected wires
may result in permanent damage to the
equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension
avant d'avoir vérifié tous les raccords de
câblage. Des fils formant un court-circuit
ou connectés de façon incorrecte
risquent d'endommager
irrémédiablement l'équipement.
