Test buttons are available for each zone to
assist in determining the correct hookup of
each of the valves.

UNPACKING AND INSPECTION

After unpacking, inspect your controller and
check for any damage that may have
occurred during shipment.
Check for proper operation of power switch
by turning the switch on and off with no
voltage applied.
Check all electrical connectors for visual
damage.
If any damaged is observed, return the
controller
to
D-M-E
replacement.

Connection of Trigger Signal
Using the cable supplied with the controller,
connect the controller to the injection
molding machine.
accomplish this is to supply a dry contact
(relay) closure that is triggered by the
injection forward signal of the molding
machine. A solid state relay contact can be
also be used. It should source power from
contact A to contact C.
Alternatively, a limit switch that is operated
from mold closure can be used as the
trigger signal.
The limit switch can be
mounted to the tie bar to catch the closing
of the moving half of the mold. It may also
be mounted to the mold to detect contact of
the mold halves.
Contact B of the connector supplies a
ground signal to provide shielding of the
cable assembly.

Trigger Signal Connection
Connection of Controller to Valves
Use an appropriate length DB-025 cable
with a male connector on one and a female
on the other to connect from the controller
to the valves. The cable must have
conductors with a minimum size of 20
gauge to run hydraulic valves.
Conductor numbers 1, 2, 3 and 4 supply
+24 VDC power to valves 1, 2, 3 and 4,
respectively. Conductor 13 supplies ground
to all of the valves.
Connection of AC Power to Controller
The standard offering of the controller is
provided with a 120 VAC connector. The
controller is designed to run from any
voltage between 88 VAC and 264 VAC.
Connect the brown conductor of the power
cable to L1 (or hot), the blue conductor to L2
(or neutral) and the green conductor with the
yellow stripe to ground. Do not operate the
controller without the ground conductor
connected.

OPERATION

Timer Setup
Do not perform this step until all electrical
connections are performed.
Turn controller power on. The timer displays
should illuminate. If they do not illuminate,
see the Maintenance and Repair sections
below.
Each timer unit has two internal timers.
Timer 1 sets the delay between when the
trigger signal is received and the valve is to
open. This is referred to as the "delay"
