AGM300 - Current Loop Interfaces

Optional 4–20 mAdc Outputs

Upon installation of the optional 4–20 mAdc Interface Board (Page 7) (P/N 3015-3133), the AGM300 has the capability of providing dual 4-20 mAdc scrolling current loop outputs for connection to external monitoring devices.

The interfaces are set up as follows: Loop 1 indicates zone area Loop 2 indicates PPM

Connection

The external devices are connected to the AGM300 using a shielded dual twisted pair cable. Use any of the remaining service knockouts to gain access to the interior of the monitor. Locate the Dual 4–20 mAdc Output connector (Page 7) and remove it from the circuit board. Secure the wire leads to the connector orienting them as shown in the diagram below. Check to make sure the polarity matches the wiring at the external device. When you are through securing the connections, carefully plug the connector back onto the circuit board.

NOTE: When one or both current loop outputs are not used, install a jumper wire between the ground the unused loop terminal(s) to prevent the system from generating a current loop fault.

CAUTION - The loop outputs have isolated grounds. Therefore, the cable shield should be terminated at the receiver and not at the AGM300. The signal for both current loops must be returned to the AGM300.
