PROGRAM OUTPUTS MODULE
Presets 1 and 2 can activate relay Outputs 1 and 2 respectively. They can be
assigned to the Process Count, Rate Indication display, or None. Output 2 has
the same programmable options as Output 1. Presets 3 and 4 can activate solid
state Outputs 3 and 4 respectively. Outputs 3 & 4 can be assigned to the Batch
Count, Total Count, Process Count, Rate indication display, or None. The
preset values are automatically assigned to the appropriate display. Outputs 3
and 4 have the same programmable options as Output 1, except they do not have
the Out End Mode option. Boundary mode is not available when the output is
assigned to the Batch counter. 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 flowchart on the
following page 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.
Note: The state of the relay, if used, is the same as the solid state output.
OUTPUT MODES - TIMED, LATCHED OR BOUNDARY
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 appears 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) is 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. 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 outputs 1 or 2 are programmed for boundary, the Output End (Reset) Modes are
not applicable and therefore do 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. ON/OFF 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 - On & Off Delay:
This mode prevents output state change for specified delay period
when turning on or off.
