OVERVIEW
This screen is the top level of the general configura-
tion parameters. It allows programming of the time and
date, along with specifications as to how the time will
be displayed (12 or 24 hour format). In addition, the
chiller configuration, as determined by the state of the
Microboard Program Jumpers and Program Switches
is displayed. A qualified Service Technician estab-
lishes this configuration per the desired operation. This
screen also serves as a gateway to more subscreens for
defining general system parameters.

PROGRAMMABLE
Clock (Enabled / Disabled)
Access Level Required: OPERATOR
Allows the user to enable or disable the Real Time
Clock in order to conserve battery life. The clock will
be disabled during manufacturing and must be enabled
at system commissioning. In addition, when preparing
for prolonged shutdown the clock should once again
be disabled. With the 031-03630-007 microboard this
setting may be changed but has no effect. The battery
in the 03630 microboard will last for over 10 years.
Present Time
Access Level Required: OPERATOR
Allows the user to specify the present time. This value
is critical to logging system shutdowns accurately and
for utilizing the scheduling capabilities. When prompt-
ed to enter a time value, the user must enter the hour
and minute desired (using leading zeroes as necessary).
If the chiller is presently set to 24-hour mode, the time
must be entered in the 24-hour format. Otherwise, the
user must also select AM or PM for the entered time. If
out of range, the user is prompted for the information
again. At this point the user may retry the time entry, or
cancel the programming attempt.
