PARAMETER MENU
Module 4 is the programming module for the Cycle Counter Parameters. In the
Display Mode, the CNT annunciator indicates the Cycle Counter display is
currently being shown. An EXCHANGE PARAMETER LISTS feature, which
includes the Cycle Counter Start and Stop Values, is explained in Module 2.
This parameter selects the source from which a count is added to or
subtracted from the Cycle Counter. Select if the Cycle Counter is not
being used, which will exit the module and bypass the remaining parameters.
When is selected, a count is generated each time the User 1 Input is
activated. When selected as the count source, User Input 1 can still be
programmed to perform a User Function described in Module 2, if desired. In
this case, the Cycle Counter would be counting the number of times the
particular User Function occurred.
The Timer Reset ( ) selection generates a count when either a manual
or automatic reset occurs. (See Module 6 for programming Automatic Resets.)
The Output ON/OFF selections generate a count when the chosen output
either activates or deactivates. These selections only appear when a Setpoint
Card is installed. O3 and O4 selections only appear for Quad Setpoint cards.
CYCLE COUNTER COUNT SOURCE
ª
«
Counting direction can be reversed through a User Input. (See Module 2.)
CYCLE COUNTER COUNTING DIRECTION
ª
«
The Cycle Counter returns to this value whenever a Cycle Counter Reset
occurs. Non-zero values are normally used for “down counting” applications,
but they can also provide an “offset” value when counting up.
CYCLE COUNTER START VALUE
ª
«
to 999
The Cycle Counter stops counting when this value is reached, regardless of
the operation of the Timer. Selecting will display the sub-menu where
the Stop Value can be set or changed. The Stop condition is cleared when a
Cycle Counter Reset occurs. Select
if a Stop Value is not used.

CYCLE COUNTER RESET AT POWER-UP
The Cycle Counter can be programmed to Reset at each meter power-up.

PARAMETER MENU
This module can only be accessed if a Setpoint Card is installed.
* Only the value parameters which apply to the selected mode will appear.
- Interval Timing (Edge Triggered) INt-E
- Interval Timing (Level Triggered) INt-L
- On-Delay/Interval Timing dLYINt
- Repeat Cycle Timing rEPEAt
- Off-Delay Timing OF-dLY
- On-Delay Timing ON-dLY
This parameter is used to select Predefined Operating Modes for the Timer.
These modes cover a variety of timing applications frequently encountered in
industrial control processes. When using a Predefined mode, the operator needs
only to set the actual Setpoint On/Off or Time-out values for the particular
application. However, each programming parameter will still be accessible, in
order to make modifications to the predefined settings if desired.
PREDEFINED TIMER OPERATING MODE
ª
«
The Predefined modes control the activation and deactivation of Output 1, in
relation to Start and Reset signals applied to the Timer inputs. (See timing
diagrams which follow.) When a selection other than
is chosen, the
parameters for Setpoint 1 ( ) in Module 6 are automatically configured to
implement the selected operating mode. For some modes, parameters in
Modules 1 and 2 are also automatically configured to properly implement the
predefined mode. Refer to the chart shown with the timing diagrams for the
specific parameters loaded for each predefined mode. Also, note the specific
external wiring or plug jumper settings required for some modes.
The Setpoint On/Off or Time-out values for the specific application should
be entered directly in Module 5 after selecting the operating mode. Only the
value parameters which apply to the selected mode are displayed. These values
can also be entered through Module 6, Setpoint (Alarm) Parameters, if desired.
Select if not using a Predefined Operating Mode, in which case Setpoint
parameters must all be individually programmed for the particular application.
