TB9: SENSOR POWER:
Refer to Appendix A for an illustration and more details. Connect power conductor (red) from either:
+5 V out to SM-module TB1 +5 V
OR
+12-24 V out to SM-module TB2 +12-24 V
WARNING:
Do not connect ‘+12-24 V Out’ terminal on the OS-6 to the SM-module TB1 ‘+5 V’. This will damage the SM-module
and void the warranty.
Power Connection
Disconnect power before opening the case to access the OS-6. Use only one of the following two methods to power the OS-6:
1.
AC Adapter (included): 12-24 VDC, 300 mA (minimum), barrel connector. Refer to Tech Note P-101 at
www.ecosensors.com/support for additional AC adapter specifications.
2.
TB1: 12-24 VDC, 300 mA (minimum), wired connection (16-26 gauge)
Initial Operation & Warm-Up
All standard connections between the OS-6 and the SM-module are made at the factory. Once power is connected to the OS-6 using one of
the methods described above, the green power/data LED will illuminate and then blink at a 1-second interval as data is received from the SM-
module. The LCD will display digits.
Power the OS-6 and connected SM-module for 1-hour before response testing. Prior to on-site process integration, operate on power for 24
hours. We recommend testing the instrument for positive response with an ozone generator when the instrument is received and again at the
site where the instrument is installed.
Set Point and Alarm Condition Settings
Five push-buttons are mounted on the circuit board
behind the wiring compartment cover. Remove the cover
(two screws) and locate the buttons in the upper-left
corner. From left to right, they are: FAIL, MAX, MIN,
INCR and DECR.
FAIL
: Time (in minutes) that the ozone level can remain
above MAX set point or below MIN set point before the
'‘Unable to Control Ozone” indicator and relay engage. To
disable the “Unable to Control Ozone” indicator and relay
(TB6), set FAIL to 0999 (available on instruments shipped
after 2012-10-15, call us for details).
MAX
: Maximum ozone set point at which the generator is
turned off.
MIN
: Minimum ozone set point at which the generator is turned on.
INCR
: Increase set point value.
DECR
: Decrease set point value.
Change a set point by pressing FAIL, MAX, or MIN. The current value of that set point will appear on the display. Press INCR or DECR to
adjust the value. MIN will not adjust higher than MAX.
Use either
FAIL MAX MIN INCR DECR
