the protective alarms.

DESCRIPTION
All the elements in the front panel of the PTE-100-C are thoroughly de-
scribed here. In-depth explanation of their use is given in the Operation
section.
Many buttons, namely those that perform a different function when held down,
effectively actuate when released, rather than when pressed. These buttons will
produce a “secondary function” when pressed until an audible beep is heard.
We will now describe the PTE-100-C along the following sections:
MAIN AC SUPPLY
POWER OUTPUT SECTION
AUXILIARY VOLTAGE
TIMER SECTION
SPECIAL FUNCTIONS
COMMUNICATIONS
MAIN AC SUPPLY
An AC supply block at the lower left-hand corner of
the front panel groups the power cord plug, a fuse
holder and the main on/off switch. Internal filters
prevent most AC perturbations from leaking into the
unit. The OFF position is indicated by a tiny circle in one of the faces of the
main switch.
Main Protection Fuses
The active (12A, Fast) fuse and a spare fuse
are included in the fuse holder. All the fuses
accessible from the front panel are standard,
5x20 mm cylindrical, and their current rating
and type are clearly printed.
