Intended Use

The UtiliGuard Series receivers are designed to locate buried pipes and cables. Over 70 frequencies and four modes of operation are available to suit your specific locating needs. The UtiliGuard B receiver is offered without all options described and will be configured when ordered.

The T5 and T12 transmitters place signals on target cables to be detected by UtiliGuard Series receivers. These units can be configured to send over 70 frequencies as well as custom frequencies. The transmitters place a signal on the cable through either direct connection, induction clamping, or broadcast modes.

The system is designed for operation in temperatures typically experienced in earth moving and construction work environments. Use in any other way is considered contrary to the intended use. The UtiliGuard Series system should be operated only by persons familiar with its particular characteristics and acquainted with the relevant safety procedures. The system should be serviced only by Ditch Witch repair centers.

IEC Safety Definitions

Hazardous voltage--electrical shock or equipment damage can result if transmitter is connected to live cable. Have qualified utility personnel disconnect both ends of cable before working.

IEC protection class II or double insulated electrical device is one which has been designed in such a way that it does not require a safety connection to electrical ground. In a device of this class, no single failure can result in dangerous voltage becoming exposed so that it might cause an electrical shock. This characteristic must be achieved without relying on a grounded metal casing.
