Page 3: Introduction
This manual contains information for the installation and operation of the PM4-IV2 panel mount monitor. The PM4-IV2 is a dual bargraph with dual isolated input panel meter display. This instrument may be configured to accept an input signal of 4 to 20mA, 0 to 2VDC or 0 to 20VDC. - Page 4 Acessing setup for scaling, relays and display brightess Use the method below to access the display scaling, relay high and low setpoints and brightness level setup. Note that DIP switch 4 must be in the ON position to access the scaling functions and in the OFF position to access the alarm relay and brightness functions.

Page 15: Alarm Relay And Brightness Level Settings
Alarm relay and brightness level settings The rear pushbuttons are used to set the alarm relays and display brightness levels. The rear DIP switch 4 must be in the OFF position to allow the alarm relays and brightness levels to be set. Alarm relays A high alarm or a low alarm setting can be stored for each relay. - Page 16 Brightness level settings The display brightness can be set using the rear pushbuttons. If required 2 levels can be set and switched via an external switch. Setting the brightness level Refer to section for details of how to access the setup functions for relay and brightness adjust- ment.
