JUICE GOOSE CQ15 Series Manual

CQ15 Series
SEQUENCED POWER CONTROL
CQ 1515 and CQ 1520

GENERAL DESCRIPTION

The Juice Goose CQ-1515, CQ-1520 and other CQ Series models provide a convenient and economical means
of remotely activating AC power to turn audio equipment and similar components on and off in a proper sequence.
CQ Series products need no additional controllers or programming. Each contains the circuitry to be activated by
another CQ, an RC Series accessory or a simple contact closure. When connected with control lines each will
automatically turn on and off in coordination with other CQ devices. All power down sequences are exact reversals
of the power up sequences.

OPERATION

The CQ-1515 (15 amp) and CQ-1520 (20 amp) are rack mount, plug-in models featuring AC surge protection and
seven power outputs. They can be used by themselves, activated via remote control or included with a more ex-
tensive power sequencing system with other CQ units. In a typical audio system the rack mounted CQ is used to
apply power to the "front-of-house" equipment before turning on amplifiers. The first CQ in the series may be
linked by way of eight wire modular cable (RJ45) to another CQ device. No time delay settings or additional equip-
ment are required. All CQ units will automatically turn on and off in the proper order.
The CQ-1515 and CQ-1520 feature three sequenced duplex receptacles and one unswitched single AC receptacle
on the back of the chassis. Each duplex has its own preset turn on and off timing. Because the CQ activates its
outlets in three stages it is useful as a stand-alone sequencer. Signal source and processing equipment can be
powered by the first sequence stages while amplifiers are powered by the last ones. The CQ can be triggered by
the switch on the front of the unit, by a remote latching contact closure (including those available from processor
based controllers such as Crestron) or by a Juice Goose RC5 accessory.

CONTROL LINE CONNECTION

Each CQ unit has a Sequence Signal Input and Output connector on the chassis. Coordinated activation is
achieved by "daisy chaining" all units output-to-input using 8 wire, RJ-45 cable. Design of the CQ control cable is
similar to but not identical to Ethernet cable. Consult the CQ Series Owners Manual before assembling the cable.
This control link allows any CQ device to be installed at any stage in a power sequencing system. Sequence tim-
ing is controlled by a nominal 8 VDC "Outputs Active" circuit between the units which is regenerated with each CQ
module. There is no limit to the number of CQ devices that can be connected and no practical distance limit be-
tween them.

SEQUENCE TIMING

Standard delay time between sequence up and sequence down events is 2 seconds. That can be adjusted in the
CQ 1515 and CQ 1520 by changing position of two DIP switches located on the main control circuit board. Timing
options are 2 seconds (standard), 10 seconds, 20 seconds and 30 seconds.
