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.
WIRING
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.

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
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
s m l l a r e d - a i m t e r e h s o u d l
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
