Proceed PDSD - Manual (Page 76)

76
MY ON SCREEN DISPLAY HAS INDICATED THAT IT HAS DETECTED
POTENTIAL AC PROBLEMS AND REFERRED ME TO THIS SECTION OF THE
MANUAL.
✓ If this is the first time you have seen the message, you probably
don’t have to do anything. If the system detects an electrical prob-
lem that might affect its operating software (an unusually strong
spike on the AC line, for example), it posts this message and
reinitializes itself automatically. Your user settings, output levels and
so forth are retained.
✓ If you see this message with any regularity, you may have a persis-
tent, severe ground loop or other AC problem that should be fixed.
We suggest you ask your dealer for assistance in isolating and solv-
ing this problem.
I LEFT THE SYSTEM ON, BUT JUST RETURNED AND FOUND IT IN STANDBY.
WHAT IS HAPPENING?
✓ There was probably a power outage while you were away from the
system. During a power failure, the PAV saves all of its critical set-
tings to nonvolatile memory. When power is restored, it enters the
standby mode and waits for your return.
MY ON SCREEN DISPLAY JUST INDICATED THAT THE PDSD WAS GETTING
TOO HOT. WHAT DO I DO NOW?
✓ The simplest thing to do is to increase the ventilation being pro-
vided to the PDSD. This situation is most likely to arise in a closed
equipment closet that include several power amplifiers which are
pre-heating the air before it even reaches the PDSD. Frequently,
opening the door to the closet or providing additional ventilation
some other way is all that is needed.
✓ If adding adequate ventilation is impractical, contact your dealer
about the optional, internally-mounted, temperature-controlled fan
kit Madrigal offers for such cases. See what you can do about tem-
porarily increasing ventilation until the fan is installed. (If the tem-
perature of the PDSD continues to rise, it will shut itself down be-
fore any damage can occur.)
