P643 Totalizer 1 Contact Closure, External The value of this parameter represents a multiple of 32 ms of contact closure for remote totalizer 1. The value is automatically calculated upon entry of P1 (design rate) and P638 (totalizer 1 resolution, external) so that the duration of contact closure allows the transistor switch response to track the total, up to the design rate. The value can be changed to suit specific contact closure requirements, such as in the case of programmable logic controllers. If a message E2 is displayed, P638 has to be increased. Entry:
1 = 32 ms 2 = 64 3 = 96 4 = 128 5 = 160 6 = 192 7 = 224 8 = 256 9 = 288 P644 Totalizer 2 Contact Closure, External Parameters The value of this parameter represents a multiple of 32 ms of contact closure for remote totalizer 2. The value is automatically calculated upon entry of P1 (design rate) and P639 (totalizer 2 resolution, external) so that the duration of contact closure allows the transistor switch response to track the total, up to the design rate. The value can be changed to suit specific contact closure requirements, such as in the case of programmable logic controllers. If a message E2 is displayed, P639 has to be increased. Entry:
1 = 32 ms 6 = 192 2 = 64 7 = 224 3 = 96 8 = 256 4 = 128 9 = 288 5 = 160 P647 Totalizer Display Selects the totalizer combination to be displayed, either manually through the scroll display key or automatically by control of the display mode (P081). Entry: 1 = totalizer 1 2 = totalizer 2 3 = totalizers 1 and 2 Page 60 Milltronics BW100 - INSTRUCTION MANUAL 7ML19985DJ01
