General
The PTX800D is a scalable pulse counter/rate indicator for digital pulse
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 PTX800D can be supplied with
two alarm channels and/or an analogue retransmit output.
Alarm conditions are indicated by the LEDs above buttons marked AL1
(for alarm channel one) and AL2 (for alarm channel two).
Manually clearing tripped alarms
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.
