RE-ALARM TIME — This variable specifies the amount of
time that will be allowed to elapse between re-alarms. A re-
alarm occurs when the conditions that caused the initial alarm
continue to persist for the number of minutes specified in this
decision. Re-alarming will continue to occur at the specified in-
terval until the condition causing the alarm is corrected. This
variable can only be changed with the Touch Pilot display,
ComfortVIEW, or Network Service Tool. This variable cannot
be changed with the Navigator display. To configure this option
with the Touch Pilot display:
ALARM SYSTEM NAME — This variable specifies the
system element name that will appear in the alarms generated
by the unit control. The name can be up to 8 alphanumeric
characters in length. This variable can only be changed when
using the Touch Pilot display, ComfortVIEW, or Network
Service Tool. This variable cannot be changed with the
Navigator display.
To configure this option with the Touch Pilot display:
Daylight Saving Time Configuration — The
30XW chiller control contains software which can automati-
cally correct for daylight saving time. This software is accessi-
ble from the Touch Pilot display, ComfortVIEW, or Network
Service Tool. It is not accessible through the Navigator display.
To enable this feature, Daylight Saving Select must be set to
1. The start of Daylight Saving must be configured by setting
the Month, Day of Week, and Week of Month. The end for
Daylight Saving must also be configured. To configure this op-
tion with the Touch Pilot display, see Table 32.
Table 32 — Daylight Savings Time Configuration
Capacity Control Overrides — The following ca-
pacity control overrides (Active Capacity Override, CAP.S)
will modify the normal operation routine. If any of the override
conditions listed below are satisfied, the override will deter-
mine the capacity change instead of the normal control. Over-
rides are listed by priority order and are often linked to unit op-
erating modes. See Table 33 for a list of overrides. See the Op-
erating Modes section on page 54 for more information
regarding operating modes.
Override #1: Cooler Freeze Protection
— This override at-
tempts to avoid the freeze protection alarm. If the Leaving
Water Temperature is less than Brine Freeze Set Point (Brine
Freeze Setpoint, LOSP) + 2.0° F (1.1º C) then a stage of
capacity is removed.
NOTE: The freeze set point is 34 F (1.1 C) for fresh water
systems (Cooler Fluid Type, FLUD=1). The freeze set point
is Brine Freeze Set Point (Brine Freeze Setpoint, LOSP), for
Medium Temperature Brine systems (Cooler Fluid Type,
FLUD=2).
