Magnum Venus Plastech DP-1000 (EPO3) - Manual (Page 16)

Choose an arbitrary length of time, such as thirty seconds and remove both pre-weighed containers from the
stream after the length of time you have chosen. If you are checking ratios by volume it is not necessary to
pre-weigh containers.
If, after checking the ratios, you have an inaccurate ratio, loosen the slave-arm and adjust slightly before re-
checking the ratios. Mark reference points on the slave arm with a pencil after each adjustment.
You may need to repeat material ratio test before you get the variable-stroke pump set correctly. If this is the
case, be sure to empty and weigh the test containers again before collecting fluid for testing the ratios.
When the correct setting for the slave-arm pump is found, mark the block at the front of the slave-arm bolt
block.
After you have set the pumps, you are ready to adjust the operating pressure to obtain the desired spray
pattern or the desired resin injection (RTM) flow rate, depending on your application.
Replace Unit Metal Cover
Unit metal cover should always be in place during operation of the unit to protect operator in case of high
pressure rupture.
