Low Battery Alarm

Units with serial numbers greater than 005000 allow access to an enhanced Low Battery Alarm feature. To activate this feature, change Function F14 to ON. When F14 is ON, the Link 10 displays a visual alarm when the monitored battery meets either of two conditions:

1)A settable rated compensated (Peukert) amp-hour depth of discharge is exceeded or,

2)Voltage remains below a settable level for 15 seconds or longer. When operating the Link 10 with the visual Low Battery Alarm function ON, three additional software functions are active. Two of these functions, F11 and F12, set the low amp-hours and low voltage levels which turn the visual alarm ON. Function F10 is the Low Battery Alarm OFF (Recharge) Set Point.

Visual Alarm Indication

There are two levels of visual alarm.

Level 1: The normal display alternates with a blank Bar Graph and LO appears in the numeric display.

Level 2: Once the Level 1 alarm display is acknowledged by the operator by pressing either SET or SEL once, the Level 2 Alarm flashes the amp- hours function light while dimming the presently displayed function light. In the event amp hours are displayed, the amp-hours light will go off at half-second intervals. Once the battery alarm feature is activated, a visual alarm display (Level 1 or Level 2) will continue until amp hours are above the Low Battery Alarm OFF (Recharge) Set Point (F10) and voltage is above the Low Voltage Alarm Threshold F12 for at least 15 seconds.

Alarm Circuit

Special versions of the Link 10 close a circuit to ground when either Visual Alarm level is active. This circuit may be used for audible alarms, generator staring, and so forth. Because additional internal circuitry is included, this option may not be retrofitted to the Link 10 in the field.
