WARNING
AFTER CHANGING THE ACCESS CODES ON THE TRANSMITTER, TEST THE UNIT BY
TURNING IT ON AND OFF NEAR THE APPROPRIATE RECEIVER. IF THE RECEIVER DOES NOT
RESPOND, DO NOT ACTIVATE A FUNCTION BUTTON! THE TRANSMITTER MAY HAVE THE
WRONG ACCESS CODE, WHICH COULD MOVE ANOTHER CRANE. RE-CHECK THE ACCESS
CODE IN THE TRANSMITTER AND RETEST. FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN SERIOUS INJURY OR DEATH AND DAMAGE TO EQUIPMENT.
7-1.3.
Receiver Access Code Setting.
The access code is preset at the factory and should not be changed unless absolutely necessary. The access
code switches are labeled “B” and “A”. See Figure 9-1. Receiver Layout for switch location.
The programming in the receiver(s) must match the transmitter. If looking at the label on the outside of the
transmitter, take note that positions “A” and “B” number from the left 1 through 8.
NOTE
IN EVENT PROGRAMMING OF ACCESS CODES IS REQUIRED, TAKE SPECIAL
CARE TO
CORRECTLY LOCATE ACCESS CODE SWITCHES A AND B. LOOK FOR THE LABELS A AND B
ON THE PRINTED CIRCUIT BOARD NEAR THE RESPECTIVE SWITCHES. DETERMINE THEIR
ORIENTATION. THE SWITCHES MAY NUMBER FROM LEFT TO RIGHT OR RIGHT TO LEFT.
LOOK FOR THE NUMBERING ON THE SWITCHES. MATCH ACCESS CODES A1, A2, - -- B1, B2
ETC.
After changing the access code, test the receiver (s) with a matching transmitter. (If the red LED DS9
comes ON in either receiver the code does not match, recheck the access code settings.
WARNING
THE ACCESS CODES IN THE RECEIVER ARE UNIQUE AND FACTORY PRESET. DO NOT
CHANGE THESE ACCESS CODES UNLESS YOU ARE REPLACING AN EXISTING RECEIVER
AND ITS ACCESS CODE. CHANGING THIS CODE COULD MAKE IT COMMON WITH ANOTHER
RECEIVER ACCESS CODE, WHICH COULD MOVE ANOTHER CRANE. NO TWO SYSTEMS IN
ANY LOCATION SHOULD EVER HAVE THE SAME ACCESS CODES INDEPENDENT OF
FREQUENCY. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS INJURY OR
DEATH AND DAMAGE TO EQUIPMENT.
7-2.
Receiver Frequency Programming.
The TR12 receiver is equipped with a frequency synthesizer that allows frequencies to be easily changed
without retuning. Normally the frequency does not have to be changed; the unit comes programmed to a
specific frequency listed on the Frequency and Access Code Label on the TR12 receiver door.
7-2.1.
RF Receiver Board Frequency Synthesizer
.
Located in the TR12 receiver is the RF Receiver Board. The circuitry on this board contains a digital
oscillator and synthesizer that are controlled by a microprocessor. This eliminates the need for specific
