Installation, Operation and Technical Manual

6.2.2 Test Mode

This is a special mode of system operation allowing service personnel to perform system
tests without permanent parameters change and altering system operating history (Alarm
Log).
To activate Test Mode move to Password Setup sub-menu and enter "TESTMODE" as the
password. The features of the Test Mode are:
Unrestricted parameters editing
-
Edited parameters will not be stored in permanent memory (EEPROM)
-
Alarms will not be recorded in the Alarm Log
-
- Alarm Log can not be cleared
- Password can not be changed
Status of security function can not be changed
-
While test mode is active a prompt "Test Mode" will alternate with current operating mode
on the bottom line of the "home" screen.
Upon quitting the Test Mode (see Par. 6.6) parameters values will be restored to original
settings.
Note: There is no timeout or any other means of automatic cancellation of the Test Mode.
It is the responsibility of the personnel to return the system to normal operating mode.

6.2.3 Entering and moving through different Menus

To scroll through the MCSU-4 menu from top to bottom, just press the INC button. The
screens that will appear are shown in section 6.6.
If the DEC button is pressed, the screen at the bottom of the menu will appear first and will
be followed by the other screens in reverse order. This can be useful when it is desired to
access a screen near the bottom of the menu.
To enter the other menus, momentarily press the relevant button - SMR, BATT or ALARM
LOG. The associated menu contents are shown in sections 6.7, 6.7.2, 6.9 and 6.10.
If at any time it is necessary to return to the MCSU-4 or "home" menu, just press the
current menu button once. E.g. if the present menu being scrolled is BATT, just press
BATT button again and the screen will return to the default "home" screen.
The INC and DEC keys are also used to increase or decrease parameter values when the
parameters are programmable.
In this case, press ENTER first. The parameter value will begin flashing on and off. Press
INC to increase the value or DEC to decrease the value until the desired value is obtained.
Then press ENTER again to actually enter the value into memory.

6.2.4 When an alarm condition exists

If one or more alarm conditions exist at any time the following message will alternate with
the "home" screen for 2 seconds every six seconds in addition to warning LED indicators:
