Resetting Ross DM2 DSV Faults
If your Ross DM2 DSV faults when air is first applied to the unit, one or both poppets may
have been jarred into a faulted position during shipment. When the poppets are faulted, input
air can escape through the muffler port. To reset the fault, air must be applied to the DSV to
return the poppets to their unfaulted position.
If the fault occurs before the unit has been wired, the problem will be signalled by air escaping
from the muffler port when input air is applied to the DSV. To reset the unit, press the brass
button on the bottom of the Reset solenoid while air is being applied to the DSV (see
Figure 5-4).
If the fault occurs after the unit has been wired, an F47 error will appear on the WPC 1000
display. To clear the fault and reset the DSV, press Reset/Select and turn the Stroke Select
key switch to OFF, then to one of the other operating modes (see page 5-11).
If you have trouble resetting the DSV, the problem may be that both poppets are faulted,
requiring more air for a reset than can be supplied by the system. In this case, try resetting the
unit with the muffler port obstructed. Place your hands or a rag or plastic packaging material
over the muffler to restrict the escape of air, then actuate the Reset solenoid.
If the DSV still will not reset, check to see if there are restrictions in the air supply line (e.g.,
restrictive fittings, quick-disconnect fittings, low flow filters or regulators, or clogged filter
elements) and correct if necessary. Also, check to make sure that the air supply line matches
the inlet port size of the DSV, and replace with a properly-sized supply line if it doesn’t.
