ESC Schedules and Conditions (Installer Setup\ESC\
Modes\Custom)
NOTE:
Pause will override the Start Charging 1, 2 and 3 schedules. User-defined criteria / conditions
will determine if the external source is actually shut off/paused during a Pause Charging
Schedule.
DEFINE SCHEDULES FOR:
Prohibit Operation -
a valid schedule will override Emergency Charging
Use Prohibit Operation to prevent the charging source from ever running automatically - no conditions are
programmable
Emergency Charging
-
always scheduled, and can't be disabled
Only allows charging to prevent a user-defined condition. Default condition is the LVD setting for a duration
defined by user. Conditions can be customized.
Pause Charging
Use Pause Charging to define conditions when
charging operation will be interrupted or resumed. There are
no default conditions, but custom conditions can be added.
Start Charging (Charging 1,2 and 3)
Use Start and Stop Charging hours to define conditions when
the
charging source will charge the batteries.
Default condition is a battery voltage and duration defined by user. Conditions can be customized.
ESC SCHEDULE PRESET DROP-DOWN OPTIONS
On Schedule
(available in Pause, Prohibit, and Start Charging 1, 2, 3)
Conditions needn't be added for this setting. It sets the criteria to TRUE always, so the ESC schedule
is always TRUE during the user-defined scheduled hours. Custom Start and/or Stop criteria can also
be set to govern On Schedule timing - see, "Defining Conditions and Groups", below, for details.
Emergency Charging Presets:
• Avoid LVD
• Low Battery voltage

Start Charging (Charging 1,2 and 3)
can be designated using
:
• On Schedule timing. Conditions can be customized.
• Low Battery / complete Bulk - voltage and time. Conditions can be customized and scheduled.
• Low Battery / complete Absorption - voltage and time. Conditions can be customized and
scheduled.
• Low SOC / complete Bulk - depending on system configuration, conditions can be customized
and scheduled.
• Low SOC / complete Absorption - depending on system configuration, conditions can be
customized and scheduled.
• Large DC load / Reduced DC load - current and time. Conditions can be customized and
scheduled.
DEFINING CONDITIONS and GROUPS

means customize conditions or toggle to view more scheduling routines.
The Start and Stop conditions are set within ESC scheduling. If a schedule is activated because a
Start condition is met, the operation will only cease if and when the paired Stop condition is met.
Four different types of conditions can be used: Simple Condition, Variable Comparison, Range
Condition, Event. Each condition type is populated with a default variable, and offers a drop-down
list of optional variables for customization.
Simple Condition
Specify a delay after which the external source will START or STOP when a chosen variable meets a
chosen relational comparison with a chosen threshold value
Variable Comparison
Specify a delay after which when the external source will START or STOP when two chosen variables
meet a chosen relational comparison
Range Condition
Specify a delay after which when the external source will START or STOP when a chosen variable is
within a range of specified values
Event
Specify a delay after which the external source will START or STOP when a chosen event has
occurred
