NOTE: Brackets indicate setting for transformer in use. See marking on Power Assembly’s shield to
determine the installed transformer and use the primary taps voltage in the corresponding brackets to
determine jumper position. “( )” indicates primary voltages for the (106V/115V/200V/212V) transformer,
“| |” for the |226V/366V/392V/450V| transformer, and “[ ]” for the [212V/505V/530V572V].
a CAUTION: Potential to cause electrostatic damage to electronic components. Before handling
electronic components, ensure that you are discharged of static electricity by briefly touching
a grounded metal object. Flowserve recommends the use of a wrist strap grounded to an
appropriate ground.
STEP 2 – LCS/MAIN BOARD
Assemble the LCS/Main board into the actuator control cover using four (4) M4x8 screws.
STEP 3
Connect the yellow 12-pin wire cable harness from the 54-point terminal block to the J5 header.
STEP 4
Connect the two-wire blue cable harness from the 54-point terminal block to header J3.
STEP 5
Connect the grey keyed ribbon cable harness from the 54-point terminal block to header J4.
STEP 6
Connect the blue keyed 18-pin/wire cable harness from the 54-point terminal block to header J8.
STEP 7 – POWER BOARD
Install the three (3) standoffs (#1-55) into the housing mounting.
STEP 8
Install the power board complete with the electromechanical starter using the M4 power board
mounting screws. Position power assembly over the three mounting screw heads (#1-45). Rotate the
subassembly in clockwise (CW) direction until all three screws are seated in the key slots.
NOTE: The keyhole slots in the mounting plate (#8-1) are spaced in such a way that the control module
assembly will mount in only one position.
Tighten the three screws (#1-45) with a 3 mm hex key.
STEP 9
Plug the 3-pin Molex harness (L1-L3) to plug into motor reverser. Plug the two (2) two-wire and
thermistor cable (T1-3) to the motor leads.
