ERROR CHECK MODE (Err Chc)
This is the first selection in the main menu. Enter the main menu and activate the SELECT/RESET switch when ‘Chc’ is shown on the left side of the display and ‘Err’ is shown on the right side of the display ‘dsP’ will be shown on the left side of the display and ‘Err’ on the right side of the display. To see the errors activate the SELECT/RESET switch. The controller will display each error for approximately 5 seconds. Once all errors have been shown, ‘Clr’ will be shown on the left side of the display and ‘Err’ on the right side. Activate the SELECT/RESET switch to clear the errors and return to the normal operating mode.
If it is not necessary to see what errors have been logged, but only to clear them, activate the MENU/SET switch when ‘dsP’ ‘Err’ is shown. The ‘Clr’ ‘Err’ selection will be displayed. Activate the SELECT/RESET switch to clear the errors and return to the normal operating mode.

This is the second selection in the main menu. It is used for testing detector operation without activating alarm outputs. To enter this mode, first enter the main menu, toggle through the selections using the MENU/SET switch and activate the SELECT/RESET switch when ‘bPS’ is shown on the right side of the display ‘Ch' will be shown on the left side of the display and the UV seen by the detector is shown on the right side of the display in counts per second.
Activating the SELECT/RESET switch while a channel is in bypass will perform the manual vi test. A significant increase in the counts per second should be observed on the lower display.
A range between 150 and 400 cps is expected.
Activating the MENU/SET switch will toggle through all of the active channels and then show ‘test’ on the left side of the display and ‘bPS’ on the right side of the display. In this manual test mode, all alarm outputs are inhibited, but the faceplate indicators will operate as in the normal operating mode. If a flame occurs or UV test lamp is used to activate the detectors the faceplate indicators operate as in the normal operating mode, but the alarm outputs will not activate. To exit the bypass mode, activate the SELECT/RESET switch while ‘test bPS’ is displayed.
SPECIAL FUNCTION MENU
To enter the special function menu activate both switches simultaneously for 20 seconds, until ‘FoP’ is shown on the right side of the display. This menu is a little harder to enter because it is not intended for general use. The items in this menu are used for system maintenance and calibration of equipment.
FORCED CURRENT OUTPUT MODE (FoP)
The forced current output mode is used to check the current output calibration and the operation of any devices connected to the current outputs.
