Possible reasons and advice
•
Check the supply voltage on D1
(see page 110**).
•
Check that the voltage in the
backup battery is > 2.8 V and that
the battery jumper is connected
(see page 110**).
•
If the message appeared once, a
tube arc may have disturbed the
program.
If the "Err 37" occurs repeatedly,
the single tank must be checked
according to section "Error
diagnosis HT and single tank". If
the function of the single tank is OK
and "USE 37" occurs repeatedly,
replace D1.
See "Err 37". If "Err 38" is the only
message in the history memory, it
will not be necessary to replace
D1. These statistics are only used in
the factory.
•
Batteries not charged.
•
Defective batteries.
•
Defective battery charger D201
(see section "Battery circuit and
power transmission unit").
This mode is only used at the factory.
To quit this mode, put switch S1:2 in
the OFF position.
