4.4 Mode 4: Testing and adjusting AUX-connection
When the indicator light
❹
is blinking white (normal AUX-mode) or a blinking red (inversed
AUX-mode, see chapter 5.1.), you may:
• Test the AUX-connection:
• Toggle the AUX1 output ON/OFF by pressing the Adjustment button
❶
• Toggle the AUX2 output ON/OFF by pressing the Adjustment button
❷
• Toggle AUX-mode to "normal" or "inversed" by pressing and holding the Adjustment
button
❶
for five seconds:
• Normal AUX-mode selected: indicator light
❹
blinks white
• Inversed AUX-mode selected: indicator light

To exit manual adjustment mode 4, press OK button
❸
once. The stove guard and AUX
signals will return to their normal operating state.
5. OPTIONAL FEATURES
5.1 AUX-connection (optional)
GARO PCU6.3 and PCU6.1 power control units
Ⓒ
are equipped with two auxiliary output
signals AUX1 and AUX2 compatible with most automation and security systems. They can
be used to send real-time status information of the stove guard.
5.1.1 Electrical specifications
• Optoisolated and potential-free AUX-
outputs: no galvanic connection
between the GARO system and the
automation system.
• When the AUX outputs are active (ON),
the optoisolator’s output transistors
will be held in conducting mode, thus
enabling current flow from IN to OUT.
This connection can be used exactly as
a relay’s contact, however the direction
and amount of the current flow must
be controlled as specified below. If
necessary, the output states can also be
inversed (see chapter 5.1.6).
• Maximum IN-OUT voltage is 24 VDC.
• Maximum IN-OUT current is 10 mA.
• Only DC voltage between IN-OUT, no
AC is permitted!
5.1.2 Coupling AUX-wire to the power
control units PCU6.3 and PCU6.1
Connect AUX-
wire to the
screw terminal.
Route the AUX-
wire through the
strain relief.
Mount the cover of the power
control unit
Ⓒ
with the screws and
ensure that the AUX-wire is properly
placed on the strain relief.
