Daikin Microtech III — руководство по экстренному отключению и настройке датчиков [42/100]

Daikin Microtech III [42/100] Emergency shutdown
Emergency Shutdown
The terminals 105 & 106 on TB2 can be used for any eld
supplied component that requires a unit emergency shutdown.
When these terminals are used, the factory installed jumper
must be removed.
Larger tonnage 16 to 28 ton Rebel models use terminals 202,
203, 204, 205, 206, as a series of terminals when not used by
an external device to open the circuit to DI4 have a mechanical
jumper connecting the terminals in numeric order.
NOTE: Emergency shutdown Faults can be set to
automatically clear once the condition that caused
the alarm is corrected. This can be accomplished
by navigating to Service menu/Alarm Conguration/
alarm cong, and changing the default of ManClr to
AutoClr.

Scroll up to “Apply Changes” and select “yes” which will
cause the controller to restart.
Enter password 6363 then scroll down to “Commission

Scroll down to “Min OA setup” menu and click on it.
Scroll down to Min OA reset and select “IAQ VDC” or
“IAQ mA” depending on the type of sensor installed.
Scroll up to “Apply Changes” and select “yes” which will
cause the controller to restart.

On all style units (MPS/DPS/RTU/SCU) the CO
2
sensor
needs to be wired to terminals X1 and M at the MicroTech III
Controller. Terminal M is the common for all analog inputs.
Make sure the eld wiring polarity is correct to read a valid
PPM value. See Table 5 on page 26
NOTE: The CO
2
sensor (and all eld installed devices)
must be powered from the same transformer as the
controller to prevent damage to the controller.
As products evolve into more sophisticated and complex machines it requires some basic changes
to wiring schematics. The specic terminal numbers to use has to be veried by referring to the
electrical prints supplied with the unit in question. However these terminals will always be in the circuit
interrupting electrical voltage to Digital input four, (DI4).
