If quick calibration changeover is to be activated remotely, connect the AUX+ and AUX- inputs
appropriately. Connect sinking drivers or contacts to the AUX- terminal and connect AUX+ to the +24V
power source. Connect sourcing drivers to the AUX+ terminal and connect AUX- to COM.
Determining Firmware Version
From time to time, as improvements are made to Prime Controls products, the firmware controlling the
units is revised. When setting a unit up or troubleshooting it may be necessary to determine the version
number for the firmware installed in your unit. The version numbers are of the form 1.00 and are
incremented either by tenths (1.01, 1.02, etc.) for small revisions or by the integer digit (1.00, 2.00, etc.)
for more significant revisions.
To determine the version of the firmware running in your unit, hold the calibration pushbutton in as
power is applied to the unit. The revision number is displayed directly on the digital display.
The two channels of the SD220/SD230 are independent and may be running different versions of
firmware. Each must be checked separately.
MAINTENANCE
The SD220/SD230 Controller requires no periodic maintenance beyond maintaining general cleanliness
of the controller, connections, and probes. Probes should be inspected and cleaned to prevent build up
of ferrous particles on the sensing surfaces. The frequency of inspection depends on the operating
conditions of the probes. Use a damp, not wet, cloth or sponge to clean the painted surfaces of the
controller. Mild soap or detergent may also be used. Dry with a soft rag.
TROUBLESHOOTING
If the display is not on, check the +24V DC power applied to the unit. Once the display is operational,
refer to displayed fault codes according to “Fault Message Interpertation” under Operation, Calibration
(page 2). If the displayed values rapidly change while the machine is static, check for loose or damaged
probe cables or improper routing of the these cables such as routing the cables with other high voltage,
or high current wires, power wires, or other noise sources.
