◎
There is a built-in fan-lock protection circuit. The output of all modules will shut off when the DC fan stops operating (fan-lock, loose
connector, or broken wires). Please turn off the AC power and remove the conditions causing fan-lock. If there are no observable
causes for fan-lock, please remove the unit from your system and send back to our local distributor or MEAN WELL for repair.
5.8 Remote Control
◎ There are built-in remote ON/OFF controls for Front-End and individual output modules.
◎
Connection diagram and control logics are shown below.

Figure 5-4 shows RC1 (CN32 PIN6) and GND-P (CN32 PIN3) connection diagram.
5.6 Over Temperature Protection (OTP) and T-Alarm
◎
The Front-End has built-in thermal detection circuit. Once the internal temperature exceeds a preset value, there will be a “HIGH”
◎
When the internal temperature is within a normal value, the T-Alarm signal will be a “LOW” signal (-0.1~0.5V).
◎ .
T-Alarm's maximum sourcing current is 10mA

signal (4.5~5.5V) sent out through T-ALARM for end system to respond. If the internal temperature continues to increase and exceeds
the “safe limit” value, then the output will shut down automatically. Please switch off the AC input, remove all possible causes, and
then leave the unit to cool down to a normal working temperature (approximately 10 minutes ~ 1 hour) before re-power on.

5.8.2 Local ON/OFF
◎
The NMS-240 modules can be turned ON/OFF individually by using the “local ON/OFF” function.
◎ Figure 5-5 shows RC2 (CN81 PIN3) and GND (CN81 PIN1 or 2) connection diagram.
※
The CN32 connection accessory (included in packaging) must be connected when using the local ON/OFF function.
