Common Service Pushbutton Assemblies; Communication Modules - Ametek 90B Series Installation And Configuration Manual

Common Service Pushbutton Assemblies

The Common Service Module can be provided with Integral Pushbuttons
(Option INTB or LPPB) or no integral pushbuttons (Option NPB). In all cases,
external pushbuttons can be connected to the rear of the unit.
Option INTB uses pushbuttons on the lower right Common Service Cell and
Option LPPB has pushbuttons mounted on the Annunciator bezel which frees
up the lower right Common Service cell for a one or two point window.
Option INTB
Both options provide Silence, Acknowledge, Test and Reset Pushbuttons. Also,
The Pushbutton Assemblies include 4 diagnostic indicators.



LED Fail
Monitors all of the LED's for a short or open circuit. To identify the failed
LED, press the Test Pushbuttons and see which cell has a failed LED.


positive or negative fault to ground in the field input wiring.

Communication Modules

The optional Communication Modules plug directly into the CSM Module
through card slot 2 and provide either a serial or Ethernet output. Only one
Communication Module per CSM is allowed.
The Serial port will be active when the 'SPT' option is included in the model
number code and the Ethernet port will be active when option 'ETH' is included in
the model number code. Systems may contain both Serial and Ethernet
communications when options 'SPT' and 'ETH' are included in the model number.
