E-1400
Model E-1400 Operations Manual
The Model E-1400 monitors and processes signals from four loop / lead-in circuits, four check loop circuits, and four Vital inputs.
These inputs can be programmed to control eight Vital outputs, four primary Vital outputs and four auxiliary Vital outputs. Each of the four primary Vital outputs can be controlled by any combination of the four loop inputs and/or any combination of the four Vital inputs. In addition to the four loop inputs and four Vital inputs (as described above), the four auxiliary Vital outputs can be controlled by the four loop Health Status inputs that are continuously monitored by the processor. A loop failure will deactivate the Vital output that the loop status input and/or loop Health Status input is programmed to control. The check loop circuits can be programmed to simulate a vehicle detection (every 1 to 255 minutes) in the loop area as a means of verifying proper loop operation. The Vital outputs and Vital inputs are monitored to ensure they are in the correct state. If the state of a Vital input is not correct, the front panel LED indicator corresponding to that input will turn red and all Vital outputs will be deactivated. If the state of any Vital output is not correct, the front panel LED corresponding to that output will turn red and all Vital outputs will be deactivated.
P-1400
Model P-1400 Operations Manual
The Model P-1400 is an inductive loop processor developed to provide detection of railway equipment in small and large detection areas typically required for yard switch, interlocking, and moveable bridge occupancy detection.Switch protection can be configured to prevent sideswipe movements typically encountered in classification yards and certain flat switching operations.The P-1400 processor is designed to directly replace older technology processors that mount in ground level enclosures.Current state-of-the-art, digital loop processing technology, combined with railroad standard vital monitoring techniques and a unique self-check function provide consistent and reliable detection. In addition, expanded user selectable features provide flexibility in set up, operation, and performance of the processor.The P-1400 has four loop inputs, four check loop inputs (used to simulate a detection), and one vital input, which can be programmed to control two vital outputs.
U-1400
The U-1400 is a standalone, shelf- or wall-mount inductive loop processor developed to provide detection of railway equipment and highway vehicles in both small and large detection areas typically required for yard switch, interlocking, moveable bridge occupancy detection and quad-gate grade crossings. Current state-of-the-art, digital loop processing technology, combined with railroad standard vital monitoring techniques and a unique self-check function provide consistent and reliable detection. In addition, expanded user selectable features provide flexibility in set up, operation, and performance of the loop processor.The U-1400 has four loop inputs, four check loop inputs (used to simulate a detection), and four vital inputs, which can be programmed to control eight vital outputs.
