Basics: Normal Mode
NORMAL MODE
Allows the connected relays to be switched with
the scanner.
To Use Normal Mode:
1. Make sure the individual relays are properly connected to the
output terminals.
2. The WRS-2224 Scanner will usually be in NORMAL mode. If left in
PROGRAM mode, it will revert to NORMAL mode after 2 minutes.
If the NORMAL MODE indicator LED is OFF, press its select
button to exit the PROGRAM mode. The NORMAL MODE
indicator LED should turn ON.
3. In NORMAL MODE, the output LED will be ON if the connected
relay is on.
To switch any relay ON/OFF, press its output button.
4. A flashing LED indicates:
(a) There is a defect in the relay (or)
(b) There are 2 relays connected to the same terminal with one
relay ON and the other OFF.
Basics: Version Number
VERSION NUMBER DISPLAY
When you are in NORMAL mode and press the NORMAL
MODE select button, some output LEDs, as well as the
button's indicator LED, will flash for 10 seconds.
The combination of flashing output LEDs 1-8 (left output
terminal) indicate the version number -in binary code- of
the Relay Scanner.
If any of the output LEDs 13-20 (right output terminal) are
flashing, their combination indicates the version number
-in binary code- of the WNX-2624 Network Node attached
to the Scanner's Digital Link.
1. Any flashing output LEDs 1-8 indicate the version number of
the Relay Scanner, with any flashing LEDs 1-4 indicating the
integer after the decimal point and any flashing LEDs 5-8
indicating the integer before the decimal point.
2. The combination of flashing numbers #1-4 and #5-8 denote
the integer in binary code (see the insert at upper right).
3. When a Network Node is attached to the Digital Link, some of
the output LEDs 13-20 will be flashing. They indicate the
version number of the Network Node, with the combination of
flashing LEDs 13-16 indicating the integer after the decimal
point and the combination of flashing LEDs 17-20 indicating
the integer before the decimal point.
4. See the insert at lower right for examples of flashing LED
combinations for version numbers that may currently be in use.

Binary Code
BINARY CODE is a method of
expressing all whole numbers as
some combination of powers of the
number 2.
A power of 2 is the number of
times 2 is multiplied by itself, where
