The Annunciator lamps on EZ-220P-PLC and EZ-220PV-PLC models are visible from a distance of more than 20 feet. Most of the Text panels / operator interfaces in the industry including C-More Micro do not have these unique Annunciator lamps. C-More Micro and other text panel manufacurers typically need external annunciator lamps which costs additional money for not only lamps but also wiring which could be approximately $50 for each (including Labor and hardware). EZ-220P-PLC and EZ-220PV-PLC has 3 annunciator lamps, each of which can be programmed for 3 different colors (Red, Yellow and Green).

A small example can illustrate the importance of annunciator lamps. If we need to show the temperature status of three sections of an oven, the unique Annunciator lamps can be configured each for 3 different colors, Red for Temperature Too high, Yellow for Temperature in Caution zone and Green for Temperature OK. Thus by configuring this on the Text panel the user can save at least $150 or more by not having to provide external lamps and wiring. Even though C-More Micro has the capability of switching background colors, it can not display three colors simultaneously.

The Annunciator lamps are configured similar to pushbuttons. Once you have selected the starting address in the PLC, all of the lamp colors will be identified by the bit pairs. The color that the lamp illuminates depends on the bit assignment of the address selected.

For example, if bit 0 is OFF and bit 1 is ON, the first lamp is Green. If bit 2 is ON and bit 3 is ON, the lamp is Yellow. If bit 4 is ON and bit 5 is OFF, the third lamp will be RED. The color code chart below, which is shown in our programming software, indicates which color would be shown based on the bit values.




Every EZSeries TextPLC is shipped with printable label sheets along with Microsoft Word template for customizing Annunciator lights. Installing EZSeries TextPLC Enhanced software will give you access to “EZSeries TextPLC_Enhanced_Inserts.DOC” in EZSeries TextPLC Enhanced Panel directory. Use this word document to print your desired labels for annunciator lights on the label sheets provided. Cut the label sheet to the right size using the trim marks provided and follow the instructions.
