NEOS 30 OEM-DM-Iss.2
7. OPERATION & CONTROL
Remote DISABLE input
The NEOS Bars feature a remote DISABLE input signal (Grey or Green/Yellow wire). This may be useful for installations in which
the Bar is not used continuously and it is desirable that the Bar should be inactive when not required, or in installations in which the
operation of the Bar is to be interlocked with other machinery.
The HV supplies may be externally disabled (Standby mode) by applying any DC voltage between 3 V and 28 V to the DISABLE
input, for example by using an external switch or relay contact between the DISABLE input and 24 V, or a logic-level voltage signal.
Subsequently reducing the voltage at the DISABLE input to lessthan 0.5 V restores normal operation of the Bar.
GREY OR GREEN / YELLOW WIRE

+24V
SWITCH CLOSED - BAR IN STANDBY MODE
SWITCH OPEN - NORMAL OPERATION
In Standby mode the Bar internal HV supplies are disabled, the status LED flashes red, and the OK output is inactive (open circuit)
to indicate that ionisation is disabled. The DISABLE signal has a weak internal pull-down resistor, thus if the DISABLE signal is left
disconnected the Bar should operate normally. However, for added noise immunity it is recommended that the DISABLE input is
externally connected to 0 V (blue wire) if not required.
Voltage applied to the DISABLE input must not exceed 28 V DC, and must be of the correct positive polarity.
The Bar may be permanently damaged by connecting the DISABLE input to any voltage outside the range
of 0 V to 28 V DC.
Where the optional SPX - 0724 AC Power Supply has been ordered ensure the Power Unit is connected to
3 wire AC mains supply, Live + N Ground, and that extra Earth wire from power supply is bonded to
Ground. With this optional supply an interface cable is required to access the remote monitor feature.
