Instruction Manual Model LP and VLP MagnaValve IM:0077 Revision: C Date: 1/11/2008 Installation of Model LP/ VLP MagnaValve on a Abrasive Blast

10 Fig. 17 Since this application uses a 30:5 ratio cur-rent transformer the AC controller must be adjusted to read 30.0 full scale. Press and hold

11 The last step of the installation is to adjust the AC controller to the same operating amperage noted before at the beginning of the installation

12 Fig. 21 The amount of this cur-vature, called arc height, is an indication of the blast stream in-tensity and the value, as meas-ured on a stand

13 The advantage of using the Almen strip method lies in the ability to detect the many changes that can occur in a blast machine cleaning operation
