8.3.10 INFORMATION KEY [INF]
The [INF] key is used to request information. The 8 information categories are listed below. The names dis-
played at the MMI are in parentheses. The categories can be scrolled through with the arrow keys. For conve-
nience, however, each category is also assigned a number so that the user may access the category directly.
The key sequence for requesting information is: [INF] n [ENT], where n is the information category below:
If the optional information category number n is omitted, Category 1 (Status Info) is assumed. See Figure 8–5:
[INF] KEY MENU STRUCTURE on page 8–14 for details.
1. REQUEST DGP STATUS
This category is used to display the present status of the DGP system.
If the [ENT] key is pressed, the first item displayed is the overall status of the DGP system. If the DGP is work-
ing properly and protecting the generator, the display reads STATUS: OK. If there is a critical failure, the dis-
play reads STATUS: FAIL. If there is a non-critical failure, the display reads STATUS: WARN. If the DGP
hardware is working properly, there may be a miscellaneous status, displayed as STATUS: MISC. The above
order represents the hierarchy in which the overall status is displayed. For example, if there is a critical alarm
and a non-critical alarm, the display reads STATUS: FAIL indicating the critical alarm.
The user may use the arrow keys for further information if the status is a critical failure, a non-critical failure, or
not protecting the generator.
2. REQUEST FAULT INFORMATION
This category is used to display (or print in applicable models) information associated with any of the last three
faults that the DGP system has stored.
When [ENT] is pressed, the display prompts FAULT #?. The user presses a digit (1 to 3) followed by the [ENT]
key. (where 1 = most recent fault, 2 = second most recent fault, etc.). If there is no valid fault information avail-
able, the message NO FAULT DATA is displayed. If the user presses a number not between 1 and 3, an error
message is displayed.
The first item of the fault occurrence chosen is displayed as DATE: xx/xx/xx. Repeatedly pressing the [
