Remote temperature sensor (RTS) failure:
(R/Y-G/Y) If a fault in the RTS (such as a short circuit, open circuit, loose
terminal) occurs after the RTS has been working, the LEDs will indicate a
failure and the solar input is disconnected. However, if the controller is
restarted with a failed RTS, the controller may not detect that the RTS is
connected, and the LEDs will not indicate a problem. A TriStar meter or
the PC software can be used to determine if the RTS is working properly.
Battery voltage sense failure:
(R/Y-G/Y) If a fault in the battery sense connection (such as a short circuit,
open circuit, loose terminal) occurs after the battery sense has been working,
the LEDs will indicate a failure. However, if the controller is restarted with
the failure still present in the battery sense, the controller may not detect
that the battery sense is connected, and the LEDs will not indicate a problem.
A TriStar meter or the PC software can be used to determine
if the battery sense is working properly.
3.5 Data-Logging
The TriStar records daily records of key system information. Data is stored in
all operating modes: Charging, Load/Lighting, Diversion. In Charge mode
records are written after dusk each day. In Load and Diversion modes,
records are written every 24 hours and may not coincide with the natural day/
night cycle. The logged data can be viewed using the TriStar Digital Meter 2
or TriStar Remote Meter 2. Data can also be accessed using MSView
TM
PC
software, which is available for download on our website.
NOTE: The Data Logging feature is available in TriStar firmware version
v12 and later. Firmware update files and instructions are available on our
website.
3.6 Inspection and Maintenance
WARNING:
RISK OF ELECTRICAL SHOCK.
NO POWER OR ACCESSORY TERMINALS ARE ELECTRICALLY
ISOLATED FROM DC INPUT, AND MAY BE ENERGIZED WITH HAZARD-
OUS SOLAR VOLTAGE. UNDER CERTAIN FAULT CONDITIONS, BATTERY
COULD BECOME OVER-CHARGED. TEST BETWEEN ALL TERMINALS AND
GROUND BEFORE TOUCHING.
AVERTISSEMENT:
RISQUE DE CHOC ÉLECTRIQUE.
ON ALIMENTATION OU AUX BORNES D’ACCESSOIRES
SONT ISOLÉS ÉLECTRIQUEMENT DE L’ENTRÉE DE C.C ET DOIT
ÊTRE ALIMENTÉS À UNE TENSION DANGEREUSE SOLAIRE. SOUS CER-
TAINES CONDITIONS DE DÉFAILLANCE, LA BATTERIE POURRAIT DEVENIR
TROP CHARGÉE. TEST ENTRE TOUTES LES BORNES ET LA MASSE AVANT
DE TOUCHER.
WARNING: Shock Hazard
Disconnect all power sources to the controller before removing
the wiring box cover. Never remove the cover when voltage exists on the
TriStar-PWM power connections.
AVERTISSEMENT: Risque de décharge électrique
Un moyen de déconnexion de tous les poteaux d'alimentation doit
être fourni. Ceux-ci se déconnecte doit être intégrée dans le câblage fixe.
Ouvrir que toutes les source d'énergie se déconnecte avant de retirer le
couvercle de la contrôleur, ou accès au câblage.
The TriStar does not require routine maintenance. The following inspections
are recommended two times per year for best long-term performance.
1. Confirm the battery charging is correct for the battery type being used.
Observe the battery voltage during PWM absorption charging (green LED
blinking 1/2 second on / 1/2 second off). Adjust for temperature
compensation if an RTS is used
(see Table 4.3)
.
For load and diversion modes, confirm that the operation is correct for the
system as configured.
2. Confirm the controller is securely mounted in a clean and dry environment.
3. Confirm that the air flow around the controller is not blocked. Clean the
heat sink of any dirt or debris.
4. Inspect for dirt, nests and corrosion, and clean as required.
