Operating instructions

Selecting the Decoder Radio Frequency
The narrow band decoder module assembly stores four user-selectable
radio frequencies. The frequencies are programmed at the factory or by
the distributor prior to delivery of the satellite. A set of jumper pins, locat-
ed at the top center of the decoder module, enables the frequency to be
selected by simply placing the jumper on the appropriate pin set. In
most cases, the jumper will be configured properly by the distributor
prior to delivery. However if a frequency change is desired, place the
jumper on the pin set as indicated in Figure 7.
Important: The base station transmitter and decoder must be set to
the same frequency to enable communication.
Assigning the Satellite Address Number
Each satellite requires a 3-digit address number to enable communica-
tion with the central controller and/or a hand-held radio. The address
numbers range from 1 (001) through 255 and are issued to the satellite
through an array of eight DIP switches, located on the decoder module
assembly. See Figure 8. In the down position, the switch is Off (open)
and represents a value of 0 (zero). In the up position, the switch is On
(closed) and represents the following address number:
Sw 1 = 1 Sw 2 = 2 Sw 3 = 4 Sw 4 = 8
Sw 5 = 16 Sw 6 = 32 Sw 7 = 64 Sw 8 = 128
To set the satellite address number, place the switch or combination of
switches to the On position which provides the numerical equivalent of
the desired address number.
For example: To set satellite address number 50 (050), start with all
eight DIP switches in the Off (open) position, then close switch num-
bers 2, 5 and 6; i.e., 2 (Sw 2) +16(Sw 5) +32(Sw 6) = 50.
Note: The narrow band satellite utilzes a built-in antenna located on the frequency module assembly. If site conditions
are such that an alternate antenna is required, the optional antenna adapter kit (P/N 102-1204) is required.
Testing Satellite Operation
• Performing a Control Circuit Self Test
A self-test feature is provided to check the functionality of various key
satellite control circuits. Before performing the test, ensure the Field
Common, Pump and Station Output control switches are set to the
AUTO (down) position.
The test is initiated by positioning the TEST/RESET switch, located on the
decoder module, to the TEST position as shown in Figure 9. Testing will
begin immediately and is indicated by the audible clicks of the control
relays and momentary illumination of the LED’s on the various PCB
assemblies. The test will repeat continuously until the
TEST/RESET
switch is positioned to the center (normal operation) position.
Note: The
RESET position resets the decoder microprocessor to factory
defaults. To take affect, the satellite must be powered up with the
switch in the RESET position. The switch should be placed in the NOR-
MAL position after 15 seconds of operation.
• Performing a Station Output Test
Ensure the Field Common control switch is in the AUTO or ON position and the Pump Circuit control switch is set to the
appropriate position.
One at a time, position each Station Output control switch (if this option is installed) to the ON position and confirm
sprinkler operation.
