4.2.2.8 Individual Function Tone Setup
The middle grid area of the main screen menu is used to set the actions of the DSP-223 when a particular
function tone is received. The left most column is the function tone number. If the
Function Tone Mode
is set to single function tone, tones F1-F16 may be programmed. If the Function Tone Mode is for dual
function tone, tones F00-F99 may be programmed.
4.2.2.8.1 Tone Active
The Tone Active column allows the user to lockout a function tone in the DSP223. When a box is
checked, the DSP-223 will respond to the selected function tones and operate as programmed.
4.2.2.8.2 Relay
The Relay column allows the user to select a relay closure to be associated with a particular function
tone. Selectable options are R01, R02, or no relay. Clicking the drop down list and selecting the desired
relay will program the relay be closed immediately upon receipt of the function tone.
NOTE: R01 = F1 and R02 = F2 with reference to the schematic.
4.2.2.8.3 Relay Group
The Relay Group allows the relays to be grouped into separate functions. This sets more than one relay
to be energized at any particular time by assigning separate groups. For example, if F1 has R1 selected
as its relay, and F2 has R2 selected as its relay, setting the two Relay Group numbers to the same value
will result in: when F1 is received R1 turns on and R2 turns off. In this scenario, F1 and F2’s relays are
interlocked. If F1 and F2 have different assigned relay groups, receiving F1 does not turn off R2.
Further, if a function tone has no relay selected, but has a relay group assigned that is used by another
relay group, when that function is received, all relays in that group will be turned off. This allows R1 and
R2 to be assigned to different groups and use other function tones with the same relay group to turn them
off.
4.2.2.8.4 Relay Duration
The Relay Duration sets the relay closure time. When a function tone is received, the relay closes. After
the time expires, the relay will open. The timer entry is in milli seconds (i.e. 1000 mSec = 1 second).
Setting the relay duration to 0 latches the relay on when the function tone is received.
CAUTION: two function tones with the same relay assigned cannot have the relay close for different
durations. Therefore, if the user selects R1 for F1 and F6 and set the duration for F1 to 2000ms, the F6
relay duration entry will automatically be set to 2000ms by the application software.
