Download Apprentice II User Guide - Intelligent Lighting Controls

Overview
The ILC Apprentice II lighting controller is a microprocessor-based, programmable
lighting controller capable of advanced lighting control in a master-slave application.
It is an economical controller that can link up to 48 control points and has the capability of using
hardwired or LightSync™ data line switches. You can program the switch inputs to control any or
all of the relay outputs. The controller features ILC Softcross™ relays with true zero-cross switching.
This User Guide outlines the capabilities of the controller and its add on modules.
The ILC Apprentice II is UL and FCC approved for commercial applications.
Structure
The major components making up the
controller are:
• enclosure
• control transformer
• CPU board with integral keypad/display
• Input board(s)
• Output board(s)
• lighting relays
Enclosure – The enclosure is rated NEMA 1.
It contains a line voltage section for the
control transformers and lighting relays and
a low voltage section. Enclosures are available in 4 sizes to accommodate 4, 8, 16,
or 32 relays.
Transformer – A 40 VA multi-tap control
transformer, 120/277 VAC or optional
120/347 VAC that provides the 24 VAC
input to power the controller electronics
and input/output board(s).
CPU Board – The CPU board provides
the controller’s intelligence and memory.
Major components include:
• Keypad/display – 4-line LCD display and six
durable, comfortable push buttons.
• Power Supply – converts the 24 VAC input
to the +5, -5 and +12 VDC required by the
controller logic and communications circuits.
A power switch provides the means of energizing/de-energizing all controller electronics.
• Communications – USB port, add-on card
expansion socket.
• Override Switches – push button override
switches turn relays all ON or all OFF.

ILC Apprentice II User Manual
• Microprocessor – executes the computer
code and coordinates all controller functions
including the controller real time clock.
• Flash Memory – contains the controller
operating system and basic tasks.
• the EEProm memory– store the user-entered
operating parameters.
• Real time clock – maintains time and date for
up to 30 days without power.
Input Board(s) – Each input board provides
four (4) switch inputs.
Major components include:
• Switch Inputs – can accept input from either
2- or 3-wire momentary or maintained dry
contact devices. Each switch input features
a switch pilot LED output, which can be programmed to track the state of a single relay,
relay group or preset. The inputs are optically
isolated, noise- and surge-resistant. A switch
and pilot may be located up to 1500 feet
from the controller, provided you use a minimum of 18 gauge wire.
Output Board(s) – Each output board provides
four (4) relay outputs.
Major components include:
• Relay Outputs – Each optically isolated output switches its associated lighting relay ON
and OFF. Each output has an associated LED.
The LED lights when the output switches the
relay ON.
• Relay –
SoftCross™ Relay: Electrically held N.O or N.C.
lighting relay rated for up to 277 VAC @ 20 full
load amps.
1-Pole Relay Option: Single-pole relay capable of controlling lighting loads up to 347VAC
@ 20 full load amps.
2-Pole Relay Option: Two-pole relay capable
of controlling lighting loads up to 277VAC @ 20
full load amps per pole.
