Expansion Modules
Atlas controllers incorporate an “
Infinite Expandability Port
” (
IEP
) which allows for expansion
to the UV sensor and all other modules. Each module (including the sensor) comes with both a
male and female connection. Connect any device to the controller and all subsequent devices
are then connected into the female end of last device added in a “daisy chain” configuration.
The following optional expansion modules are available for use on Atlas UV
controllers. Contact
your authorised distributor for purchasing information.
VOLT FREE CONNECTION MODULE:
Allows for a
connection to a remote device such as a buzzer,
light, alarm system, PLC, etc., via a pair of contacts.
In normal operation the OK and COM contacts will
be connected, and in a fault condition (Low UV,
Lamp fail, Power Fail), the Fault and COM contacts
will be connected. Maximum Contact Rating is 1A-
120-230V AC/DC (use 16-22 AWG).
SOLENOID CONNECTION MODULE:
Connects a
NORMALLY CLOSED line voltage solenoid valve to
the system. On a non-monitored system, the sole-
noid will only close on a lamp failure error. On a
monitored system, the solenoid is closed when the
UV level drops below 50%. Also note that in cases
where emergency use of untreated water is re-
quired, the controller can be placed into a manual
override mode allowing for the flow of water in an
alarm condition.
4-20 mA MODULE:
Outputs a 4-20mA signal of the
UV output to a remote device such as a data logger
or computer.
ETHERNET MODULE:
Allows for all controller func-
tions to be connected to a computer via an Ether-
net cable.
