Term Definitions
1. Close/Open time: The time interval from the instant of receiving the close (open) command to the instant when all pole contacts touch (separate). 2. Close/Open simultaneity: The maximum time difference among the instants of contact touch (separation) of each break. 3. Bounce time: The time from the first contact (separation) to the final stable contact (separation) of the moving and static contacts during close (open) operation. 4. Action time: (Contact action time) The time from the instant of receiving the close (open) command to the instant when the contact just starts to move. 5. Bounce count: The number of times the moving and static contacts separate (touch) during open (close) operation. 6. Bounce amplitude: The maximum rebound value of the moving contact during its movement. 7. Stroke: The distance from the starting position to any position of the moving contact during open/close operation. 8. Open gap: The total gap between the contacts of one pole or any connected conductive parts when in the open position. 9. Over-travel: The distance the moving contact continues to move after contact touch during close operation. 10. Excess travel: The difference between the maximum stroke during the movement of the moving contact and the stroke after stabilization during open/close operation. 11. Just close (open) speed: The moving speed at the instant when the moving and static contacts touch (separate) during close (open) operation. 12. Average speed: The ratio of the stroke to the time during the entire movement of the moving contact in close (open) operation. 13. Gold short time: In close-open operation, the time interval from the instant when all pole contacts touch to the instant when all arc contacts separate in the subsequent open operation.
Printer Installation Method
(1) A-type panel: Please pinch the elastic clips on both sides of the printer frame with your hand, push the entire printer into the mounting hole of the instrument or equipment panel, and check whether the printer is installed firmly. (2) D-type and F-type front paper change panel type: Installation is extremely simple and convenient. Please insert the entire printer into the mounting hole of the instrument or equipment panel, clamp the printer from behind the equipment panel with the plastic clip and tighten the screws. ◆General paper loading process is as follows ① Remove the front cover of the printer. ② A-type panel micro printer must be removed from the instrument panel. Note: The micro printer power must be turned off before operation. D-type, F-type front paper change panel type and T-type desktop can skip this step. ③ Remove the paper roll shaft, install a new paper roll, put the paper shaft back into the guide groove of the printer, and confirm that the paper roll shaft is firmly installed and will not fall out. ④ Cut the paper end into a triangle or trim it neatly. ⑤ Turn on the printer power, after the printer advances a bit of paper, press the SEL key to turn off the SEL indicator, then press the LF key to rotate the print head, manually feed the paper head into the paper inlet below the print head, the paper will slowly enter the print head until it emerges from the front of the print head, then press LF or SEL key to stop the print head rotation → cover the printer cover, and thread the paper out through the paper outlet of the front cover. ◆Replacing the ribbon cartridge Ribbon replacement is only for dot matrix printers; thermal printers only need special thermal paper and do not require ribbon replacement (consumables). Note: Thermal paper has two sides, only the front side can be printed. ◆The process of replacing the ribbon cartridge is as follows ① Open the front cover of the printer. ② First lift the right end of the ribbon cartridge, then lift the left end (the end with the knob) to remove the ribbon cartridge. ③ Gently place the left end of the new ribbon cartridge on the gear shaft of the print head, turn the knob on the ribbon cartridge in the direction of the arrow until the end of the ribbon cartridge falls to the bottom, then put down the right end of the ribbon cartridge. ④ Install the printer cover, first hang the upper part of the front cover on the frame, pay attention to align the indicator light and buttons, then press the lower part of the front cover slightly toward the frame to snap the front cover onto the frame.
