1.5 Safety and Regulatory Information
NOTE: This section contains important information for safety and regulatory
requirements.
REMARQUE : Cette section contient des informations importantes relatives à
la sécurité et aux obligations réglementaires.
The TriStar controller is intended for installation by a qualified technician
according to electrical rules of each country in which the product will be
installed.
TriStar controllers comply with the following EMC standards:
Immunity: EN 61000-4-3: 2006; EN 61000- 4-6: 2009
Emissions: CISPR 22: 2008
Safety: EN60335-1 and EN60335-2-29 (battery chargers)
A means shall be provided to ensure all pole disconnection from the power
supply. This disconnection shall be incorporated in the fixed wiring.
Using the TriStar grounding terminal (in the wiring compartment), a perman ent
and reliable means for grounding shall be provided. The clamping of the
earthing shall be secured against accidental loosening.
The entry openings to the TriStar wiring compartment shall be protected with
conduit or with a bushing.
FCC requirements:
This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Changes or modifications not expressly approved by Morningstar for
compliance could void the user’s authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC rules. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communication.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment
on and off, the user is encouraged to try to correct the interference by one
or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numerique de la classe B est conforme a la norme NMB-003
du Canada.
1.6 Optional Accessories
Remote Temperature Sensor (RTS)
If the temperature of the system battery varies more than 5˚C (9˚F) during the year,
temperature compensated charging should be considered. Because the battery’s
chemical reactions change with temperature, it can be important to adjust charging to
account for the temperature effects. The RTS will measure the battery temperature,
and the TriStar uses this input to adjust the charging as required.
The battery charging will be corrected for temperature as follows:
• 12 V battery
– 0.030 Volts per ˚C (–0.017V per ˚F)
• 24 V battery
– 0.060 Volts per ˚C (–0.033V per ˚F)
• 48 V battery
– 0.120 Volts per ˚C (–0.067V per ˚F)
The RTS should be used only for battery charging and diversion control. Do not use
the RTS for load control. The charging parameters that are adjusted for temperature
include:
• PWM regulation
• Equalization
• Float
• High Voltage Disconnect
See Installation, Step 4, for connecting the RTS to the TriStar.
Digital Meter Displays
Two digital meters can be added to the TriStar at any time during or after installation.
One version is mounted on the controller (TS-M), the other is suitable for remote
locations (TS-RM). The manual for installation and operation of the meter displays is
included with the meter.
The display is a 2x16 LCD meter with backlighting. Four push-buttons are used to
scroll through the displays and to execute manual functions.
There are a series of display screens that provide information such as:
• operating information and data
• operating bar charts (voltage and current)
• alarms and faults
• diagnostics
• settings
In addition, there are various manual functions built into the meter. For example, the
meter can be used to reset Ah data or start/stop equalizations.
One of 5 languages can be selected for the meter.
Ethernet Communications Adapter (EMC-1)
This product is an Ethernet gateway that provides web monitoring services,
a Modbus TCP/IP server, and a local web page server. End users can
collect information about their off-grid PV system remotely. One EMC-1
supports all products with MeterBus ports by bridging MODBUS TCP/IP
requests to serve LiveView pages for each product.
USB Communications Adapter (UMC-1)
A modular unit that uses a USB-B plug, usually from a USB A-B
computer cable, and an RJ-11 plug to connect with a Morningstar
controller’s MeterBus port, for monitoring and programming using
MSView PC software.
