9500 Hardware Description
CAUTION Terminals provided on the unit shall be connected only to passive load transducers or
source transducers that apply no more than 10V to the circuit that originates from the VR9500 (or
other value that equates to not more than 33Vac RMS/46.7V peak or 70Vdc total on the circuit)
CAUTION Other than the IEC inlet for input power to the unit, terminals provided on the rear of
the unit shall be connected only to SELV / double insulated circuits of other equipment.
1.5 Maintenance
CAUTION: Remove power from the VR9500 prior to cleaning near the ventilation slots.
You should not have to carry out much preventative maintenance on the VR9500. An annual verification of the
calibration is recommended to ensure the accuracy of the controller. At the time of the annual calibration,
debris should be blown out of the ventilation slots and the fan. Verify the operation of the fan, and make sure
ventilation (as defined in the installing the controller instruction ) is maintained.
The functionality of the fan should be checked monthly and cleaned as required in a high dirt and dust
environment.
Use one of the following items to clean a VR9500 enclosure:
·
A soft, dry cloth
·
A soft cloth moistened with water
·
A soft cloth moistened with a solution of water and a gentle, non-scratch household cleaner that does not
contain ammonia
CAUTION: Never use a fuse with a higher current rating, lower voltage rating, or slower time
delay than the specified fuse. Replace fuse with same type and rating as fitted.
The VR9500 is protected by a fuse in between the power cord and the power switch. The power cord must be
removed to replace the fuse. Replace the main fuse with the same type (usually a LittleFuse 0218002.HXP) to
maintain protection against overheating, damaging the controller, and possible fire.
High Voltage Warning
CAUTION: Dangerous voltages are present w ithin the pow er supply. Disconnect pow er supply before servicing.
·
All servicing, repair, and testing of these products must be carried out by competent personnel who are
conversant with the particular hazards of AC line operated equipment and with the particular dangers of
switch mode power supplies.
·
After disconnecting the AC source, allow 5 minutes before touching the unit to allow capacitors within the
unit to discharge.
·
Heatsinks within this product may be live. Test before touching.
·
This product must be reliably earthed and professionally installed in accordance with the prevailing electrical
wiring regulations and the safety standards.
·
The internal power supply uses a 3.15A FAST ACTING 250V LBC FUSE 5 x 20mm (F1). This fuse is
accessible only to qualified service personnel. IMPORTANT: REPLACE FUSE WITH SAME TYPE AND
RATING AS THAT FITTED.
