
Wire the level sensor/float switch to the 1550+ panel utilizing the cable shown below. You will only use the black
and blue wires (dry contacts - polarity not important), carefully cut back and tape the brown and white wires. Run
the cable back to the 1550+ controller and plug into the port labeled “T. Int.”.
 Activate level sensor option, touch the level sensor button on the HMI setup screen (shown below) so the level
sensor button turns green and says “YES (DI1)”, see image below. That input is now active so when the tank level
goes low or if there is no level switch hooked up, an error will be shown on the HMI.
 Note, spraying does not stop when the tank level error is active.

Fault output – The 1550+ has an NPN output (24V/1A max.) that can be used to indicate a fault on an external
device (light, buzzer, or sent to PLC).
When the 1550+ detects a fault like a level sensor fault or a shorted nozzle cable, a fault is displayed on the HMI . If this
icon is pressed another fault screen will appear and any active faults that are present will be shown (See below).

If a fault is active it will be listed in the fault screen. The fault will only clear if it is no longer active. If fault is still
active i.e. tank level is still low, then the fault is still active and cannot be cleared. Once the tank is filled, the fault
can be reset.
