About the 8440-1810
Model 8440-1810 is manufactured by Woodward INC and is under the umbrella of the easYgen-1000 series. This model is offered for purchase as well as repair and refurbishment from AX Control INC. The model has two different voltage inputs, if the voltage is in the range of 50-130 V then the input must be a 100 V input, if the voltage is 131-480 V then the input must be 400 V input.
If a charging alternator is being put into place for applications that operate at 12 V the current limiting resistor of the alternator needs to be 105-120 Ohm or 6 Watts, if the application is 24 V then the resistor will need to be in the range of 210-240 Ohm, this will also need to be 6 Watts.
The model can be connected to a GSM modem which can also be connected to a laptop, note that if a SIM card is being used and enabled to send SMS messages a message can be sent by the GSM modem. The control can also be connected to a fixed-network modem, this is also typically known as a landline modem, if using a landline modem the Phoenix model is specifically recommended. The Phoenix modem does have a discrete input that can be used to send an alarm message.
When using the control it is best that the model is in idle mode, it will block any alarms that are labeled as under-voltage, under frequency, and under-speed, once the LM is false the alarms will be able to be monitored again.
