Parameters
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 
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
