•Operation
General
The PTX800A is a scalable totaliser/rate indicator for analogue rate
signals. It will display either the rate or total according to setup. The
other value is displayed when you hold down the
TOTAL/RATE
key.
For more complex applications, the PTX800A can be supplied with
two alarm channels and/or an analogue re-transmit output.
Alarm conditions are indicated by the LEDs above buttons marked
AL1
(for alarm channel one) and
AL2
(for alarm channel two).

The alarm channels can be set for automatic or manual reset. For
manual reset, the LED will flash when an alarm trips. These alarms will
only clear if you have acknowledged the alarm and the trip condition
has cleared. Press
AL1
or
AL2
to acknowledge the alarm.
