Omega Vehicle Security PTC900 Module 5 Timer Operating Modes, Module 4 Cycle Counter Parameters

6.4 MODULE 4 - CYCLE COUNTER PARAMETERS (	)
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.

CYCLE COUNTER COUNT SOURCE

«

ª

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 START VALUE

	«	to 999
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 STOP VALUE

«

ª

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.

« to

CYCLE COUNTER COUNTING DIRECTION

«

ª

Counting direction can be reversed through a User Input. (See Module 2.)

CYCLE COUNTER RESET AT POWER-UP

«

ª

The Cycle Counter can be programmed to Reset at each meter power-up.

6.5 MODULE 5 - TIMER OPERATING MODES (	)
This module can only be accessed if a Setpoint Card is installed.
PARAMETER MENU

* Only the value parameters which apply to the selected mode will appear.

PREDEFINED TIMER OPERATING MODE

«ON-dLY- On-Delay Timing OF-dLY- Off-Delay Timing

ªrEPEAt - Repeat Cycle Timing

dLYINt	- On-Delay/Interval Timing
INt-L	- Interval Timing (Level Triggered)
INt-E	- Interval Timing (Edge Triggered)

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.

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.
