The M60 and M66 crossover manifold systems are comprised of two separate
regulators housed in a common body. The two regulators are each attached to
separate source cylinders. One of the regulators has an adjustment knob that rotates
270 degrees to enable source side selection. The other is preset to an appropriate
setting for the system outlet range. The source selection knob adjusts the outlet
pressure to be either above or below the preset side. An arrow on the selection knob
points to the cylinder side delivering gas and away from the standby cylinder. The
outlet pressure of the delivery side is approximately 15-30 psig (1-2 bar) higher than
the standby side. Rotating the knob to point to the standby side, changes the
pressure differential such that the standby side now becomes the delivery side.
As the delivery side cylinder becomes empty and the pressure drops below the
pressure of the standby side, gas begins to flow from the standby side. The source
selection knob is then turned to what was the standby side and the empty cylinder
may now be replaced without interrupting process flow.
