and the mark has to grant the movement during bead build up, heat soak
phase and bead roll over!
8.2.3 Calculating of the fusion pressure
The fusion pressure is the sum of the “table value + movement pressure”
(e.g. 31 bar* + 6 bar = 37 bar)
* for ECOS 315 and ECOS 250 PE d 200 mm, SDR 11 see pressure tables
8.2.4 Adjusting of the fusion pressure
15. Open completely the machine.
16. Reduce pressure with the fine-adjustment pressure valve (turn counter-clockwise).
17. Move control lever towards “close ><” position and increase the pressure on the
pressure valve (turn clockwise) until clamping carriage moves smoothly.
18. Adjust fusion pressure with the fine adjustment pressure valve as soon as both pipe
ends are in contact (turn clockwise, keep control lever in position close).
If the fusion pressure is set too high, re-adjust:
1. Open completely the machine.
2. Turn the fine-adjustment pressure valve approx. 3 revolutions counter clockwise.
3. Start fusion pressure adjustment again.
