switch on the front cover (or activate the remote
TEST input) when the CO level is below the alarm
level (minus the hysteresis/deadband).
The Manual Reset also applies to the buzzer alarm. If
the buzzer alarm is active, pressing the TEST switch
will temporarily silence the buzzer. But to reset the
buzzer alarm to the Normal Mode, the CO level
must have dropped below the value of the trip level
(minus the hysteresis/deadband) when the TEST
switch is pressed.
Test Mode
The Test function allows verification of the output
and relay operation, and the Test time duration can
be programmed via the menu. The Test mode func-
tion is disabled by default and must be enabled via
the menu to later operate while in Normal mode.
Test mode can only be activated while the device is
in Normal mode (not if the device is in Fault, Alarm,
or ReCal modes).
To initiate the Test function (if enabled) during Nor-
mal mode, either press and hold the TEST button for
1 second or activate it remotely by shorting the TEST
+ to TEST – (COM). This will cause the Status LED to
blink red, the analog output to go to 100%, and both
relays (if installed) to activate. The buzzer will also
beep once every 15 seconds (if enabled), and the LCD
will indicate Test mode and remaining time. The
Test function will continue for 5 minutes (default),
and then the device will reset to normal operation.
The Test function can be cancelled by pressing the
TEST button a second time.
Fault Mode
The Fault mode function is disabled by default,
and it must be enabled via the menu to operate. The
Fault function will monitor the CO sensor lifetime
and indicate when the CO sensor should be re-
placed. If the device determines that the sensor has
reached the end of its useful life and that replace-
ment is necessary, it will enter Fault mode. This will
cause the Status LED to blink red and the buzzer to
beep once every 10 minutes. The LCD display will
periodically show “Sensor Fault.” The Fault mode
can be disabled via the menu or enabled at any time.
If enabled, and the device is in Fault mode, press-
ing the TEST button will “silence” the buzzer due to
the Fault alarm only. Buzzer silence due to the Fault
alarm will hold until the fault condition is reset via
the menu. (The buzzer may still activate due to a CO
setpoint alarm if enabled.)
Configuration
WARNING
All commercial CO sensors have a finite life. The
life expectancy of these models is 5 to 7 years. They
must be replaced periodically to ensure reliable
operation in detecting conditions that are potentially
hazardous to human health and safety.
ReCal (Recalibration) Mode
The ReCal mode function is enabled by default and
must be disabled via the menu if it is not required.
The ReCal function will monitor the device and in-
dicate when the CO sensor should be recalibrated. If
the device determines that the sensor requires recali-
bration, it will enter ReCal mode. This will cause the
Status LED to blink red and the buzzer to beep once
every 10 minutes. The LCD will periodically show
“ReCal Required.” If enabled, and the device is in
ReCal mode, pressing the TEST button will silence
the buzzer due to the ReCal alarm only. Buzzer
silence due to the ReCal alarm will hold until the Re-
Cal condition is reset via the menu. (The buzzer may
still activate due to a CO setpoint alarm if enabled.)
Operation parameters default to typical values but
can be configured locally via the user menu using
the LCD display and the three push-buttons on the
circuit board. Any changes made are saved in non-
volatile memory and are restored in case of a power
loss. Only the menu items relevant to the device
model and selections will be shown.
The menu can be accessed at any time after the
warm-up mode. If there is 5 minutes of inactivity the
menu will close and normal operation will continue.
The TEST button has no effect when the menu is in
use.
Menu item values are controlled by using the three
buttons on the circuit board (ROLL, MENU, and
SAVE). To enter the menu, press and release the
<MENU> key. This will enter the menu Step 1, and
pressing the <MENU> key a second time advances to
Step 2. Each press of the <MENU> key advances the
menu item. No values are saved or changed by using
the <MENU> key.
The <ROLL> key is used to make changes to
program values by scrolling through the available
options. Holding the <ROLL> key pressed will scroll
through some options at a faster rate.
