Program

The front panel buttons are used to program the counter and to display and set the P1 and P2 presets. All the buttons can be disabled by the Keyboard Inhibit input. (see Programming, page 6).

Auto Reset (see and on3 page 35)

When Auto Reset is on, the counter will be automatically reset as follows:

In Reset to Zero mode, the counter will reset to zero when P1 is reached.

In Reset to P1 mode, the counter will reset to P1 when zero is reached.

Front Panel Reset and External Reset (RST / Ext. Reset)

A Reset can be caused by pressing the RST button or by applying a signal to the External Reset input. Any active relay will be returned to its normal condition.

If the operation of the External Reset is safety critical, it is recommended that the External Reset signal is derived from an independent power supply which will remain stable if the 7922's supply is interrupted.

P1 and P2 Presets

The minimum value possible for P1 and P2 is 000001, except in Dual Preset

mode, when P2 can be set to zero. P1 and P2 must be greater than any

multiplying prescaler value, or the unit may not operate correctly.

The P1 preset can be set at any time.

In Reset to Zero mode, the change will be accepted immediately.

In Reset to P1 mode, the change will not be accepted until after a Reset.

The P2 preset can be set as shown below.

The change will be accepted immediately.

Count Modes (see page 35)

The diagrams show how the P1 and P2 Relays are controlled by the Count, by Batch Total and by Reset.

The diagrams show how the Count is reset to zero or P1 by Auto Reset. In all modes, the Count can be reset at any time by a RST/Ext. Reset.

The counter can count up to 999999, and or down to -99999. Beyond these limits, the counter will continue to count internally, but the display will flash 999999 or -99999 until either the count returns to below the limit, or the counter is reset by RST/Ext. Reset.

Dual Preset Mode

In Dual Preset mode, P1 and P2 are used independently to control the operation of the counter and the relays.

Press SEL, then use the Digit buttons to change P1. The display will flash. Press SEL again to accept the new P1 value, then use the Digit buttons to change P2. Press SEL again to accept the new P2 value. If SEL is not pressed within 30 seconds of the last change to either P1 and P2, they will revert to their original values.

1 Dual Preset with Auto Reset on

Note: P1 Relay cannot be set to Latched.

Note: If P2 Relay is set to Latched, it will return to normal at the same time as P1 Relay.

2 Dual Preset with Auto Reset off

Note: If P1 or P2 Relays are set to Latched, they will return to normal at RST/Ext. Reset.

Batch Mode

In Batch mode, P1 and P2 are used in combination to control the operation of the counter and the relays.

Set P1 and P2, as shown above for Dual Preset mode.

When the Batch Total is displayed, the RST button can be used to reset it to zero.

Note: P2 relay cannot be set to Pulsed.

Note: The P2 Relay operates when the Batch Total reaches P2. It will return to normal when the Batch Total is reset to zero.

3 Batch Mode with Auto Reset on

Note: P1 relay cannot be set to Latched.

Note: The Batch Total increments at Auto Reset.

4 Batch Mode with Auto Reset off

Note: If P1 is set to Latched, it will return to normal at RST/Ext. Reset.

Note: The Batch Total increments at the first RST/Ext. Reset after P1 has been reached.

ConnectionsWARNING: This counter must not be wired the same as the 7921.

Pin Description Range
1 Aux	illary DC Supply -ve	0V - See pin 2, below
2 Aux	illary DC Supply +ve	Power Supply (see pages 37 & 38) The counter can be powered by AC mains, in which case pins 1 and 2 provide an Auxiliary supply (+12V DC +20% -10%, 75mA max recommended) which can be used to power sensors if required. Alternatively, the counter can be powered by an external DC source (12-24V DC ±10%, 100mA), connected to pins 1 and 2.

15 Input A

Inputs A and B in Unidirectional mode

In the two Unidirectional modes, the count is incremented or decremented by input A, whilst the direction is dependent on input B.

In Unidirectional High mode, both inputs are high speed inputs, suitable only for electronic signal sources, eg. transistors, proximity switches, encoders.
In Unidirectional Low mode, both inputs are low speed inputs (30Hz max), suitable for contact closure sources, eg. microswitches, relays, pushbuttons. Any contact noise is removed by filtering. They can also be used for electronic signal sources.

Inputs A and B in Quadrature mode

In Quadrature mode, the count is incremented or decremented depending on the phase difference between input A and input B.

In this mode, both inputs are high speed inputs, suitable only for electronic signal sources, eg. transistors, proximity switches, encoders.

Input K (Keyboard Inhibit) and Input R (Reset)

Both inputs are low speed inputs as described above.

Cables

Maximum wire size the connector can accept is:

2.5mm^2 cross sectional area; 1.8mm diameter. (equivalent 13 AWG solid wire)

Any signal cables connected to this device must not exceed 30 metres in length. If signal cables are installed that are routed outside the building, it will be necessary to install additional surge protection devices.

Input Polarity (see page 37)

Inputs A and B (pins 15 and 14) can be sink or source dc inputs, depending on the way they are wired, with respect to their Common input (pin 13), as shown in the examples below, and on pages 37 and 38. Pin 1 must always be connected as shown.

The opto-isolated inputs K and R (pins 5 and 4) can be sink or source ac or dc inputs, depending on the way they are wired, with respect to their Common input (pin 3), as shown in the examples below and on pages 37 and 38.

Only K and R are isolated from the supply pins.

Sink Inputs (NPN)

Source Inputs (PNP)

Note: Common Pins 3 and 13

These pins must always be correctly connected for their inputs to work.

For dc signals, to +V or -V , as shown in the examples above and on page 37.

For ac signals (5/4/3 only), as shown in example 4 on page 37.

Count Direction (see page 36)

In all modes, count direction is dependent on Reset mode (see Programming) and Sink/Source wiring, as shown in the diagrams. The count direction and the edges that trigger the count are shown by the arrows.

For unidirectional mode, the count directions obtained with input B open-circuit are marked *.

Note:

The count direction must not change in less than 25~ s , or the unit may not operate correctly.

Relays (see page 38)

The P2 relay can be programmed to be normally-open or normally-closed. In the case of the P1 relay, contact P1A can be programmed to be normally-open or normally-closed. P1B will always be the opposite of P1A.

The relays can be programmed independently to operate in pulsed or latched mode. In pulsed mode (P1 relay: Auto Reset Off only) the relay will operate for a length of time set by the program. In latched mode the relay will operate, and stay in that condition until reset.

The relays can be programmed to revert to a known safe state in the event of a power failure or on entering program mode. The three alternatives are:

Current - the contacts will remain in the same state as before the event;

Reset - the contacts will revert to their normal, unoperated state;

Set - the contacts will revert to their operated state.
