Control Panel:
The EasyTouch
®
PL4/PSL4 Control System Outdoor Control Panel with flexible hinge.
Installed in upper portion of EasyTouch PL4/PSL4 control system Power Center.
Feature Circuits:
Programmable circuits that may control relays and/or valve actuators. For details, see the
EasyTouch PL4/PSL4 Control System Systems User’s Guide (P/N 522461)
High Voltage Panel/Compartment:
Removable panel for the high voltage compartment of EasyTouch PL4/
PSL4 Power Center. The high voltage wiring including 18 V and 24 V circuit breakers, relays and GFCI.
Indoor Control Panel:
This wall mounted remote controller with LCD (liquid crystal display) is wired to the
control circuit board in the EasyTouch PL4/PSL4 control system Power Center. The control panel can be wall
mounted inside a house to control the EasyTouch PL4/PSL4 control system.
IntelliChlor
®
Salt Chlorine Generator (SCG):
Uses a process called electrolysis to produce sodium
hypochlorite (liquid chlorine) from a low concentration of salt added to the pool water. Model IC 20 Cell (P/N
520554) for pools up to 20,000 U.S. gallons (75 liters) and model IC 40 Cell (P/N 520555) for pools up to
40,000 U.S. gallons (151 liters). The external IntelliChlor Power Center (P/N 520556).
iS4 Wireless Controller:
Four function spa-side remote. Spa wall or deck mounted.
Outdoor Control Panel:
Control panel with flexible hinge installed in upper portion of Power Center to control
EasyTouch PL4/PSL4 control system.
Power Center
: Metal enclosure with power relays, transformer, and 18 V and 24 V internal circuit breakers.
Used for distributing power for controlling EasyTouch PL4/PSL4 control system.
Low Voltage Compartment:
Top compartment of Power Center for all low voltage wiring.
Low Voltage Raceway:
Vertical space in the left side of Power Center for low voltage cabling.
Main Circuit Board:
The circuit board mounted behind the EasyTouch PL4/PSL4 control system control
panel.
Relay Circuits:
The circuits that control the relays on the circuit board. Connectors on top edge of the circuit
board.
Screw Terminal Connector:
Removable connector that may attach to circuit board with multiple sockets
(anywhere from 2 to 6) to receive conductors from controllers and sensors; conductors held by screw
terminals; multiple conductors of a small enough gauge (usually 22 AWG) may be coupled to a single socket
of a terminal connector.
Salt Chlorine Generator:
Automated pool chlorinator that sanitizes using salt to produce free chlorine.
Transceiver:
Circuit board with attached antenna that can send and receive radio frequency (wireless)
transmissions. Used with QuickTouch
®
II Wireless Controller.
Wireless Controller (QuickTouch
®
II Controller):
Wireless controller for the EasyTouch PL4/PSL4 Control
System with all the functionality of the Indoor Control Panel. Connected to a transceiver which is connected to
the COM port on the main circuit board. (see IntelliChlor SCG above).
