Vickers® Switching Power Plug
For Use with Solenoid Operated Valves Rated to 24V DC
EHH-AMP-702-A-*-2* Series
This switching power plug is essentially a remote controlled on/off switch. When compared with switching
relays, it gives more consistent valve response times
and reduced de-energizing times.

Conforming to ISO 4400 (DIN 43650) interface, it has
a built-in amplifier that enables the switching control
signal for hydraulic and other types of on/off valves to
be taken directly to the valve solenoid, instead of via a
control cabinet relay.
Type of Switch
A – Direct switching of power supply

Connection Option
1 – Standard PG9 cable clamp
Features/Benefits
2 – Metric M16x1.5 cable clamp
3 – M12x1 male connector

WARNING
Reverse polarity will destroy
the connector and may cause
load malfunction.
WARNINGS
• Wire the plug for correct
polarity. Wrong polarities can
cause plug burn-out and/or
machine malfunction.
• Tighten the cable clamp to
secure the cable.
• Do not connect, or
disconnect the plug while
power is on.
nA
ll seals must be fitted correctly
at plug installation to provide
protection to IP67 (IEC 529).

Start-Up Procedure
Please refer to all safety warnings
located on page 3.
1. With the plug correctly
wired but not mounted to
the load, provide it with
24V power supply.
5. E
nsure that no damage
or injury will occur on the
machine when the valve is
operated.
2. Apply a 13V to 30V DC (24V
nominal) command signal
and check that the integral
LED illuminates. Reduce
the signal to 6V DC (or
open circuit) and check that
the LED goes out.
6. S
witch on the power
supply. Apply a command
signal to:
(a) illuminate the LED and,
(b) energize the load (e.g.
solenoid valve).
If the LED does not illuminate there is a short circuit
in the load. Replace the
load/load coil.
3. If there is a malfunction of
the LED replace the plug.
4. Switch off the power supply and the command signal and connect the plug to
the load. Ensure that the
interface seal is correctly
fitted and clamped between the mounting faces
(essential for IP67 protection). Tighten the retaining
screw.
Brown Connect with +
Blue Connect with White Connect with C
7. S
uccessful completion of
these steps means that the
plug and load are ready for
normal use.
