AVE 4PSWT operation manual Introduction, Operation, Dwell, Alarming

INTRODUCTION

The 4PSWT is a 4 position sequencing, alarming, bypassing, and homing switcher. The front panel toggle switch allows for automatic sequencing, homing, and by-passing of the 4 video inputs. Sequencing is controlled by a front panel recessed dwell pot. This pot is recessed to eliminate accidental adjustment. The dwell adjustment varies from approximately .2 second to 60 seconds.

OPERATION

The 4 toggle switches control homing, sequencing and by-passing. The LEDs above each toggle switch give a visual indication of the current camera. Homing any camera will stop the sequence mode and display the selected camera. If no homing switch is used, the switcher sequences through all cameras selected for sequencing in the loop.When a toggle switch is in the “BYPASS” position, the switcher willl drop this camera from the sequence or bypass it. When the toggle switch is in the “SEQUENCE”

position this camera is included in the sequence.

DWELL

The dwell or time that each camera appears on-screen can be adjusted by the recessed front

panel control. This can be varied from approximately .2 seconds to 60 seconds. Use a small flat bladed screwdriver to adjust this control. Turning this pot to the right increases the dwell time.

ALARMING

The alarming feature is tied to camera position 4 of the 4PSWT. The alarm input is located on the rear of the switcher. This compression type connec- tor allows for the connection of an alarm switch or other alarming device.

in the small slot below the clamp. When inserted, push the screwdriver slightly downwards to open the clamp. Now insert the wire and remove the screwdriver blade. When an alarm is connected, the switcher will always
