Troubleshooting
28 3A1602H
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 38.
2. Reverse A and B transducer electrical connections
at board, page 38. If error moves to transducer B
(Status Code 4), replace transducer A, page 37.
Status Code 4: Transducer B Failure
1. Check transducer B electrical connections (J8) at
board, page 38.
2. Reverse A and B transducer electrical connections
at board, page 38. If error moves to transducer A
(Status Code 4), replace transducer B, page 37.
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 43.
2. Short on control board. Replace board, page 37.
3. Worn or hung up motor brush causing arching of
brush at commutator. Replace brushes, page 44.

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])
