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 on 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

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.
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.
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.
Batch Mode with Auto Reset on
Note: P1 relay cannot be set to Latched.
Note: The Batch Total increments at Auto Reset.
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.
