Set Relay 9
volts DC 14.5
12 VDC Models
Range: 00.0 to 25.5
Set Relay 9
volts DC 29.0
24 VDC Models
Range: 10.0 to 35.5
Sets the voltage trip point for the auxiliary relay number 9. When the battery voltage exceeds this setting
the relay closes (engages) between the N.O. and COM terminals. Both the normally open (N.O.) and
normally closed (N.C.) contacts are available for each of these auxiliary relays. This setting is
compensated for the battery temperature when the BTS is used. There is no intentional time delay on the
reaction for this setting; this allows fast response to rapid voltage changes in the system.
R9 Hysteresis
volts DC 01.0
All Models
Range: 00.1 to 12.8
The Hysteresis Volts DC setting determines the voltage difference between when the relay opens
(disengages) and when it closes (engages). This is an “active high” type of control. The relay closes
(engages) between the N.O. and COM terminals when the battery voltage exceeds the AUX RELAY 9
VOLTS DC setting and opens (disengages) at this setting minus the R9 HYSTERESIS VOLTS DC
setting. It will remain open (disengaged) until it again reaches the AUX RELAY 9 VOLTS DC setting. (For
example, the default setting opens the relay when the voltage exceeds 14.5 VDC and closes when it
drops below 13.5 VDC for 12-volt systems). There is an intentional 2-second time delay to reduce cycling.
Set Relay 10
volts DC 14.8
12 VDC Models
Range: 00.0 to 25.5
Set Relay 10
volts DC 29.5
24 VDC Models
Range: 10.0 to 35.5
Sets the voltage trip point for the auxiliary relay number 10. This setting is compensated for the battery
temperature when using the BTS. There is no intentional time delay on the reaction for this setting. This
allows fast response to rapid voltage changes in the system.
R10 Hysteresis
volts DC 01.0
All Models
Range: 00.1 to 12.8
The hysteresis setting for relay number 10. There is an intentional 2-second time delay to reduce cycling.

Relay 11 opens on any error condition.
R9 &R10 close on batt > setpoint. Open on batt < setpoint – Hys.
MENU HEADING - BULK CHARGE TRIGGER TIMER (15)
Set Start Bulk
time 00:00
All Models
Range: 00:00 to 23:50
Starts the bulk charge process at the time shown. Setting to 00:00 defeats this function. This setting is
required when using the SLT mode so that the batteries are charged once each day. With the GRID
USAGE TIMER enabled, the START BULK TIME setting should be set near the beginning of the
charging time window for best operation. Since the battery will usually be fully charged when this timer
setting is reached, the battery charger will usually reach the ABSORPTION stage of the charging process
quickly and will then hold the battery near the BULK VOLTS DC setting for the ABSORPTION TIME
setting (default time period is 2 hours). This setting does not need to be adjusted if you are using FLT
mode with a generator. The ‘MAXIMUM AC AMPS IN’ switch must be in the AC1 position to use the
‘BULK CHARGE TRIGGER TIMER’.
INFORMATION DISPLAY
The following information is displayed as additional Menu Items.
To disable timer set to 00:00. If grid timer active set bulk time after start charge time.
In SLT mode dont disable this timer. It is daily chg time.
