Frequently Asked Questions
Q: What does the CT 1100728 battery discharge indicator do?
A: The CT 1100728 is a 24VDC panel-mount instrument that displays battery state of charge via LED indication, logs operating hours via integrated hour meter, and automatically triggers equipment lockout when battery voltage drops below a preset threshold.
Q: What is the operating voltage for the CT 1100728?
A: The CT 1100728 operates at 24VDC nominal. Verify your electric lift truck uses a 24-volt DC battery system before installation. 12VDC or other voltage systems require different indicator models.
Q: What is the hour meter resolution on the CT 1100728?
A: The CT 1100728 hour meter increments in 1/10 hour (6-minute) increments. This resolution provides precise operational time tracking for maintenance scheduling and battery cycle counting.
Q: What are the cross-reference part numbers for the CT 1100728?
A: The CT 1100728 is equivalent to OEM part numbers 1100728, CA1100728, and 110-0728. The CT 1100728 supersedes the older CA1100728 and 110-0728 designations on newer Caterpillar equipment.
Q: How does the automatic lockout feature protect the battery?
A: When battery voltage drops below the preset lockout threshold, the CT 1100728 disables truck operation automatically. This prevents deep discharge that could damage the battery or strand the truck without power.
Q: Is the CT 1100728 compatible with all Caterpillar electric lift truck models?
A: The CT 1100728 is designed for Caterpillar electric lift trucks with 24VDC systems. Confirm your truck operates at 24VDC and uses compatible panel-mount indicator connections before ordering.
