PROGRAM OUTPUTS MODULE
Presets 1 through 6 can activate solid state Outputs 1 through 6
respectively. All outputs can be assigned to the Count or Rate indication
display, or None. The preset values are automatically assigned to the
appropriate display. Outputs 3 through 6 have the same programmable
options as Output 1, except they do not have the Out End Mode option. A
manual reset, which requires the use of a User Input, overrides a timed output.
If boundary or latched is selected for the output mode the time value does not
appear as an option. The following flowchart shows only the Outputs portion:
PHASE
The positive (+) phase of an output indicates that when the display value
equals the preset value, the output turns on. When the output is reset it is
turned off. The negative (-) phase of an output indicates that when the display
value equals the preset value, the output turns off. The reset condition of the
output is the on state. When an output phase is changed, it does not take effect
until a manual reset or power down is performed.
OUTPUT MODES - TIMED, LATCHED, BOUNDARY OR HI/LO
ACTING
TIMED
For timed output operation, when the display value equals the preset value,
the output activates for the time selected. After the time value expires, the
output returns to its inactive state. The output time can be programmed from 0.01
to 99.99 seconds. An output may appear to be latched if the time delay is longer
than the time required for the counter to reach the preset value. When an output is
assigned to the rate display, the output may appear to be latched if the output time
delay is greater than the minimum update time. The output deactivates when the
rate drops below the preset value and the output time expires.
LATCHED
An output selected for the Latched Mode activates when the display value
equals the preset value. The output stays active until it is manually reset by a
User Input selected for that function. When the unit is reset, the output returns
to its inactive state.
BOUNDARY
An output selected for the Boundary mode (Hi Acting) will be active when
the display value is greater than or equal to the positive preset value. If the
display value is less than the positive preset value, the output will be inactive
state. For negative preset values, the output will be active when the count
value is less (more negative) than the negative preset value. The output will be
inactive when the display value is greater (more positive) or equal to the negative
preset value. If an output is programmed for boundary, the Output End (Reset)
Modes will not be applicable and therefore will not appear in the display.
HI/LO ACTING
This mode is used in conjunction with all Rate modes, and also with
Boundary count modes. A Lo acting output would perform the Output action
when the count/rate is lower than the preset. A Hi acting output would perform
the Output action when the count/rate is higher than or equal to the preset.
RATE OUTPUT ON/OFF DELAY
This option is available for the rate indicator and is used to prevent output
chatter. The output condition must be satisfied for a period of time longer than
the delay period for the output state to change. The minimum on or off delay
time allowed is 0.10 seconds. OFF/ON Delay is not available if output is set
for TIMED operation. If LATCHED mode is selected, the OFF DLY options
are not available.
NO DLY - No delay
ON DLY. - On Delay:
Prevents activation of output(s) for the amount of time
programmed.
OFF DLY. - Off Delay:
Prevents deactivation of output(s) for the amount of time
programmed.
OF&ON.DLY - Off & On Delay:
This mode prevents output state change for specified delay
period when turning on or off.
