Status Code 1 and 2 Settings
1. Locate switch SW2 on the control board.
2. Set the four DIP switches to the desired positions.
See F
IG. 48 and Table 2.
Status Code 3: Transducer A Failure
1. Check transducer A electrical connections (J3) at
board, page 34.
2. Reverse A and B transducer electrical connections
at board, page 34. If error moves to transducer B
(Status Code 4), replace transducer A, page 33.
Status Code 4: Transducer B Failure
1. Check transducer B electrical connections (J8) at
board, page 34.
2. Reverse A and B transducer electrical connections
at board, page 34. If error moves to transducer A
(Status Code 4), replace transducer B, page 33.
Status Code 5: Excessive Current
Draw
Shut off unit and contact distributor before resuming
operation.
1. Locked rotor: motor unable to turn. Replace motor,
page 38.
2. Short on control board. Replace board, page 33.
3. Worn or hung up motor brush causing arching of
brush at commutator. Replace brushes, page 39.

DIP Switch and Function Left Right (default setting)
DIP Switch 1
If selected, causes shutdown or displays a warning if the pres-
sure imbalance exceeds selection made in DIP Switch 2
WARNING SHUTDOWN
DIP Switch 2
If selected, causes shutdown if A and B pressure imbalance is
greater than
500 psi (3.5 MPa, 35
bar)
(60% if < 800 psi [5.6
MPa, 56 bar] running)
800 psi (5.6 MPa, 56
bar)
(70% if < 800 psi [5.6
MPa, 56 bar] running)
If selected, causes warning if A and B pressure imbalance is
greater than
300 psi (2.1 MPa, 21
bar)
(50% if < 800 psi [5.6
MPa, 56 bar] running)
500 psi (3.5 MPa, 35
bar)
(60% if < 800 psi [5.6
MPa, 56 bar] running)
DIP Switch 3
If selected, causes shutdown or displays a warning due to devi-
ation of pressure from setpoint exceeds selection made in DIP
Switch 4
WARNING SHUTDOWN
DIP Switch 4
Causes warning if deviation of pressure from setpoint is greater
than
300 psi (2.1 MPa, 21
bar)
(25% if < 800 psi [5.6
MPa, 56 bar])
500 psi (3.5 MPa, 35
bar)
(40% if < 800 psi [5.6
MPa, 56 bar])
