Programming
DIP-switch configuration
Applicable devices can be configured via DIP-switches. The DIP-switches are located on the side of the device and can be
adjusted with a small screwdriver or other implement.

Enabling DIP-switch programming disables PR 4500 communication interface programming, maintaining the ability to cycle
through the menu on the display and verify parameter values and device status. For DIP-switch programming, the non DIP-
switch programmable parameters are set at factory default values.
Calculating DIP-switch settings for Input high or setpoint settings
Calculating the decimal value from the binary setting, you derive F1 from S2.1-7 and the multiplication factor F2 from S2.8-10,
and you get:
F
setpoint/input high
= F
1
* F
2
Note: The maximum input frequency is 100,000 Hz.
Valid configuration e.g. base value = 80 and multiplier = 1000 => 80,000 Hz.
Invalid configuration e.g. base value = 127 and multiplier 1000 => 127,000 Hz.
The PR 4590 can power the PR 3225 for programming mode only. Neither the input nor the output is active in programming
mode (powered by PR 4590). Remember to cycle power for both power rail / terminals and PR 4590 (if present) to reload DIP-
switch values at power up.
When DIP-switch S1.10 = ON, the PR 3225 will load the last saved configuration during the power-up sequence. PR 3225 is
shipped from factory with all DIP-switches set to off, which selects default configuration.
