PERFORMANCE ( continued)

ENVI RONMEN TAL

SHOCK

50 g’s for 11 milliseconds.  Three shocks in both directions 
of the three mutually perpendicular axes for a total of 18 
shocks.

VIBRATION

Withstands a vibration test designed for mobile equipment 

control consisting of two parts:
1. 

Cycling from 5 to 2000 Hz in each of the three axes. 

2. 

Resonance dwell for one million cycles for each reso-
nance point in each of the three axes.

Subject to acceleration levels of 1 g to 46 g’s.  Acceleration level 
varies with frequency.

HUMIDITY

After  being  placed  in  a  controlled  atmosphere  of  95% 
humidity at 49° C (120° F) for 10 days, the EDC will perform 

TABLE C. MAXIMUM RESPONSE TIME IN SECONDS, OF STANDARD (NON-ANNULAR, NON ORIFICE), ANNULAR AND .052 ORIFICED EDCs. 
CHARGE PRESSURE IS LESS THAN 250 PSI. RETURN TO NEUTRAL TIMES ARE APPROXIMATELY 60% OF FULL TO FULL.

Two wiring styles are available:  MS and Packard connectors.  The 
MS connector is Part Number K01314 (MS3102C14S-2P) and has 
four pins, only two of which are used (A and B) for single coil 
devices.  See Connection Diagram for proper wire phasing and 
pin locations.  For both MS and Packard connectors, phasing is 
such that a positive voltage on the Red wire (Pin B) will cause a 
pressure rise at the C2 port for single coil valves.

Included in the mating Packard connector bag assembly (which 
must be ordered separately) are:

1. 

2 (or 4) 14 - 16 gauge sleeves

2. 

2 (or 4) 18 - 20 gauge sleeves

3. 

1 plastic housing

4. 

2  (or  4)  green  cable  seals  (accept  2,  2-2,  8  mm  wire 
diameter)

5. 

2 (or 4) gray cable seals (accept 2, 81-3, 49 mm wire 
diameter)

6. 

2 (or 4) blue cable seals (accept 3, 50-4, 21 mm wire 
diameter)

See Ordering Information.

To  assemble  the  female  tower  connector,  use  the  following 
directions:

1. 

Isolate the wires that extend from the command source to 
the EDC.

2. 

Strip back the insulation 5.5 millimeters on both wires.

3. 

Push a ribbed cable seal over each of the wires with the 

  .

should be 9.5 millimeters.  Thus the insulation should just 
protrude beyond the seal.

4. 

Select the larger of the two sets of pins, as measured at Di-
mension A (see Dimension A drawing), if using 14-16 gauge 
wire.  Choose the smaller if using 18-20 gauge.  Place the 
wire into the socket so that the seal edge is pushed through 
and extends slightly beyond the circular tabs that hold it 
in place.  Crimp in the locations shown in Distance, Packard

available from your local Packard distributor.
