INTENDED USE OF PRODUCT

The autoswitch monitoring system is used when status monitoring of the inlet pressure is needed. The system can be

configured with multiple remote alarms. This is particularly helpful because it provides status notification to mul-

tiple users. The system may also be configured with telephone dialers that will call the user and alert them to the low

status of up t o four autoswitches.

Connections to most of the system components are made to terminal blocks. A small flat-blade screwdriver is

required to tighten the terminal block connections on the remote alarm. Connections to the autoswitch are made

using a connector supplied by CONCOA. A soldering iron and solder are required to wire this connector. The

customer supplies all cabling that connects the system components. For more information on installation, please see

the section that applies to the particular unit.

GENERAL SAFETY PRACTICES

When using your autoswitch monitoring system, basic safety precautions must be followed to reduce the risk of fire,

electrical shock, and injury.

a. Read and understand all instructions. Follow all warnings and instructions marked on the product.

b. Install the remote alarms, dialers, or secondary remote alarms where they will not be subjected to rain or

condensation. Discontinue use of these device if it is suspected that liquids have penetrated the case; have

the device serviced.

c. Install the remote alarm and secondary remote alarm in locations where the temperature varies between 0°

and 140°F. The autoswitch may be installed in locations where the temperature varies between –40° and

140°F (-40 to 60°C).

d. Do not install the remote alarm, secondary remote alarm, or dialer in hazardous locations.

e. The nameplate on the side of the autoswitch gives instructions on installing the autoswitch in a hazardous

location.

Handle the remote alarm, dialer, or secondary remote alarm with care. If damaged or dropped, suspend use

immediately.

g. Operate the 529 5298 and 529 5300 remote alarm with the type of power source indicated on the remote

alarm. If you are not sure of your power source, contact your dealer or local power company.

h. Avoid overloading wall outlets and extensions cords; this may result in electrical shock or fire. The 120 VAC

remote alarm input is rated to 0.4 Amps; the 220 VAC remote alarm input is rated to 0.4 Amps.

Never push objects of any kind inside the case as the objects may touch dangerous voltage points or may

short parts that could result in the risk of electrical shock or fire.

Protect the power cord or any other connecting cables, and do not use if any wires are frayed, damaged, or

loose.

DESCRIPTION OF PRODUCT

Autoswitch

The autoswitch provides visual alarm status only. The left/right banks both have alarm LED's. The LED's will

illuminate when the right/left bank pressure is below the alarm set point on the switchover inlet gauge. The LED's

will turn off when the left/right bank pressure is above the alarm set point. The autoswitch power LED will be lit

when the remote alarm is connected, and the remote alarm switch is on. If the power LED is not on, the electronics

are not functioning.

Slide the red tab seen on the autoswitch inlet gauge to adjust the alarm set point. Note that CONCOA does not

recommend lowering the factory set point of the alarm system. When adjustments are made, check the function of

the system. Pressurize the system and shut off the inlet pressure to both sides. Allow the inlet pressure on the right
