5.1 Customer service
For customer service:
• Phone 1–303–652–4400 or 1–800–776–6543 within the U.S.A.
• Email custserv@helixtechnology.com .
Damage requiring service
Shut off power to the module and refer servicing to qualified service
personnel under the following conditions:
a. If any liquid has been spilled onto, or objects have fallen into, the
module.
b. If a circuit board is faulty.
c. If the Convectron gauge sensing wire is open or the gauge is
contaminated.
d. If the module has been exposed to moisture.
e. If the module does not operate normally even if you follow the
operating instructions. Adjust only those controls that are explained in
this instruction manual. Improper adjustment of other controls may
result in damage and will often require extensive work by a qualified
technician to restore the module to its normal operation.
f. If the module has been dropped or the enclosure has been damaged.
g. If the module exhibits a distinct change in performance.
If the module requires repair:
• See pages 61–65,
• Phone 1–303–652–4400 or 1–800–776–6543 within the U.S.A., or
• Email custserv@helixtechnology.com .
5.2 Troubleshooting
If any of the conditions described on page 61 have occurred,
troubleshooting is required to determine the repairs that are necessary.
Precautions
Because the Convectron gauge contains static-sensitive electronic parts,
follow these precautions while troubleshooting:
• Use a grounded, conductive work surface. Wear a high impedance
ground strap for personal protection.
• Do not operate the module with static sensitive devices or other
components removed from the product.
• Do not handle static sensitive devices more than absolutely necessary,
and only when wearing a ground strap.
• Rely on voltage measurements for troubleshooting module circuitry. Do
not use an ohmmeter.
• Use a grounded, electrostatic discharge safe soldering iron.
