Draper EZ Pad Plus Operating Instructions

1 This equipment should not be installed, operated or maintained by any
person who has not read all the contents of these instructions.
2 Operates on 110-120v AC, 60 Hz current.
3 Before connecting switches, controls, or electrical, make sure power is
off. Wiring indicated in diagram by dashed lines must be completed by
an electrician.
4 Locate the Touch Panel so it is within clear view of the equipment being
operated; it should also be in a location that will minimize the chance of
damage.
1 Mount Relay Boxes in desired location (suggested in a position to minimize
high voltage wire runs) and connect circuits as outlined in Wiring Notes.
2 Connect gym equipment or similar devices and auxiliary devices to relays
in Relay Box as outlined in Wiring Notes. As connections are completed,
fill in a relay assignment worksheet (see page 4). Copy this page as
necessary to match your network requirements.
3 Mount Touch Pads in desired location. Touch Pads require a standard
8 / " x 4½" electrical box (RACO Box #942 or equivalent).

4 Make low voltage connections between Touch Pads and Relay Boxes and
Relay Box to Relay Box (if multiple Relay Boxes are in network) as outlined
in Wiring Notes.
5 Set Relay Box address as outlined in Setting Box Addresses for Relay
Boxes.
6 Program User Codes as outlined in Programming Passwords for EZ Pad
Plus Touch Pad.
7 Configure system Relay Boxes as outlined in Define Relay Box Addresses
for EZ Pad Plus Touch Pad.
8 Program desired groups as outlined in Programming Groups for EZ Pad
Plus Touch Pad.
Wiring Notes
1 Connecting Relay Box to 120 Volt Power Source:
a) The 3-position screw terminal strip at the top center of each relay board
is to provide power to the relays that is in turn distributed to the
connected devices.
b) If using only one board of relays, the relay board with relays 1-4 must be
used since the processor pulls power from this circuit.
c) Input circuit size is determined by load ratings of devices connected to
each bank of relays Draper suggests that each bank of relays be
connected to a dedicated 30 amp circuit.
d) Wire size will be determined by connected load and distance from power
source and distance to farthest device to be operated.
2 Connecting gym equipment or other directional devices to Relay Box:
a) There are three screw terminal strips located next to each of the eight
relay sets in each Relay Box that are labeled UP, DOWN and NEUTRAL.
UP and DOWN are the hot supply lines that become active when the
relay is on.
b) Connect backstops, dividers, electric height adjusters or other directional
items to be operated to these relay sets.
c) Wire size will be determined by load rating of items connected to source
and total distance from power source to the device.
3 Connecting auxiliary devices to Relay Box:
a) The positions labeled AUX 1 and AUX 2 are for auxiliary outputs
that have their own power supply (230VAC -30A-max), such as lights,
scoreboards, PA system, etc.
b) One connection is to be made to the hot wire of the supply. The other
connection becomes hot when the relay for the auxiliary output is on.

Caution
Overview
Printed in U.S.A.
The relay is continuous contact, and operates just like a switch opening
and closing the hot wire.
4 Wiring the 4-position screw terminal on the Relay Box.
a) Use minimum 18 gauge shielded cable for all low voltage connections
b) You need to connect to all four terminals (TRX+, TRX-, +12DC and
GND) for each touch pad being connected. If you have multiple touch
pads, you should connect one touch pad to Relay Box "0". Other touch
pads can be connected to this same Relay Box or any other Relay Box
on the network,
c) The TRX+ and TRX- lines are for communication. It is only necessary to
connect these two lines between relay panels on the network.
5 Wiring the 4-position screw terminal on the touch pad.
a) Use minimum 18 gauge shielded cable for all low voltage connections.
b) It is necessary to connect all four terminals (TRX+, TRX-, +12DC and
GND) to four conductor cables running from relay panel(s). If you have
multiple touch pads, you should connect one touch pad to Relay Box
"0". Other touch pads can be connected to this same Relay Box or any
other Relay Box on the network. Be careful to keep the same polarity as
on the Relay Box.
Setting Box Addresses for Relay Boxes
Up to sixteen Relay Boxes can be controlled by one keypad. This section
explains how to set up the relay box address.
The 4-position dipswitch inside the Relay Box sets the box address.
The following table shows the state of the dipswitch positions. NOTE: Box
addresses are permanently set only after the unit is re-powered.
When the box address is set, this determines the index of the relays in the
box. Each box contains 8 pairs of relays for driving motors, one relay for up
and one for down. Each pair of relays has an index associated with it.
For example relays 1 and 2 in box address 0 will be Relay Set 1. Relays
1 and 2 in box address 1 will be Relay Set 9 and so on. This is important for
programming which relay set will control which apparatus.
Each box also has two auxiliary outputs for driving other gymnasium
apparatus such as scoreboards, PA systems, etc. There can be up to 16
outputs, 9 and 10 are in box address 0, and 19 and 20 are in box address 1
and so on (see table below).
Please Note: Installer should complete Relay Assignment Worksheets
(see page 4) as assignments are made.
