Status Code 3: Transducer A Failure
1. Check transducer A electrical connection (J3) at the
board. See F
IG
. 14, page 42.
2. Reverse A and B transducer electrical connections
at the board, page 42. If the error moves to
transducer B (Status Code 4), replace transducer A.
See
Pressure Transducers , page 43.
Status Code 4: Transducer B Failure
1. Check transducer B electrical connection (J8) at the
board. See F
IG
. 14, page 42.
2. Reverse A and B transducer electrical connections
at the board, page 42. If the error moves to
transducer A (Status Code 3), replace transducer B.
See
Pressure Transducers , page 43.
Status Code 5: Excessive Current Draw
Shut off the unit and contact distributor before resuming
operation.
1. Locked rotor; motor unable to turn. Replace the
motor. See Electric Motor , page 46.
2. Short on control board. Replace the board. See
Control Board , page 41.
3. Worn or hung up motor brush causing arcing of
brush at commutator. Replace the brushes. See
Motor Brushes , page 46.
Status Code 6: High Motor Temperature
The motor is running too hot.
1. The motor temperature too high. Reduce the
pressure duty cycle, gun tip size, or move Reactor
E-10 to a cooler location. Allow 1 hour for cooling.
2. Check the fan operation. Clean the fan and motor
housing.
Status Code 7: No Cycle Counter Switch
Input
Have not received input from cycle counter switch for 10
seconds after selecting Recirc mode.
1. Check the cycle counter switch connection to the
board (J10, pins 5, 6). See F
IG
. 14, page 42.
2. Check that the magnet (224) and cycle counter
switch (223) are in place under the B side motor end
cover (227). Replace if necessary.
Table 5: Status Code 1 and 2 Settings
DIP Switch and Function Left Right (default setting)
DIP Switch 1
If selected, causes shutdown or displays a warning if the
pressure 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
deviation 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])
