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

P1 Preset

The P1 preset can be set at any time. The minimum value possible is 000001. P1 must be greater than any multiplying prescaler value, or the unit may not operate correctly.

0 Count/ Time P1

SEL P1 0 0 0 0 0 5 P1 SEL

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

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.

Auto Reset (see and on page 35 and on page 36)

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 7932's supply is interrupted.

Counter Modes (see page 35)

The diagrams show how the Relay is controlled by the Count, and by RST/Ext. Reset. The diagrams show how the Count is controlled by the Input signal.

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 RST/Ext. Reset.

In Reset to Zero mode, the counter can count up to 999999. In Reset to P1 mode, the counter can count from P1 down to -99999. At these limits, the display will flash until RST/Ext. Reset.

1 Counter with Auto Reset on

Note: The relay cannot be set to Latched.

2 Counter with Auto Reset off

Note: If the relay is set to Latched, it will return to its normal condition at RST/Ext. Reset.

Timer Modes (see page 36)

The diagrams show how the Relay is controlled by the Timer, and by RST/Ext. Reset.

The diagrams show how the Time is controlled by the Input signal and by the Pause setting.

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

In Reset to Zero mode, the timer can time up to 999999. In Reset to P1 mode, the timer can time from P1 down to zero.

1, 2imer with Pause enabled

Note: When the Input signal is removed, timing stops. When the Input signal is re-applied, the unit continues to time from this previous value.

3, 4imer with Pause disabled

Note: When the Input signal is removed, timing stops. When the Input signal is re-applied, the unit resets to zero or P1, and starts timing from this value.

1. Timer with Auto Reset on

Note: The relay cannot be set to Latched.

2, 4Timer with Auto Reset off

Note: On reaching P1, timing will stop, but a RST/Ext. Reset will restart it.

Note: If the relay is set to Latched, it will return to its normal condition at RST/Ext. Reset.

High Speed Inputs

These are high speed inputs (10kHz max), suitable only for electronic signal sources, eg. transistors, proximity switches, encoders.

Low Speed Inputs

These 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.

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 pages 37 and 38)

Inputs CH and K (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 CT 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 CT and R are isolated from the supply pins.

Sink (NPN) Inputs

+V 13 14 K CH 15 -V

+V 3 4 R 5 CT -V

Source (PNP) Inputs

+V 15 CH 14 K 13 1 -V

+V 5 CT 4 R 3 -V

Note: Common Pins 13 and 3

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 examples 3 and 4 on page 37.

Count and Timing Direction

In all modes, count and timing direction is dependent on Reset mode (see Programming). Either Input CH or Input CT can be used in Counter mode, but only Input CT can be used in Timer mode (see Programming).

The count direction and the edges that trigger the count are shown by the arrows:

Relay (see page 38)

This is a single pole double throw relay, with a common contact, a normally open contact, and a normally closed contact. The Relay State indicator on the front panel shows the state of the normally open contact.

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

The relay 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.

Programming

- To enter Programming mode, press and hold PGM for 3 seconds. The display counts down 3..2..1.

Prescaling

A multiplying or dividing factor can be used. If a multiplying prescaler of n is used, the counter will count: 0, n, 2n, 3n etc. If a dividing prescaler of n is used, the counter will increment or decrement on every nth input pulse.

Changes in the prescaler are not effective until after exit from Program mode, AND THEN AFTER a Reset.

WARNING

INSTALLATION AND MAINTENANCE MUST BE CARRIED OUT BY SUITABLY QUALIFIED PERSONNEL ONLY. HAZARDOUS VOLTAGES MAY BE PRESENT ON THE CONNECTION TERMINALS.

Installation

This product is intended to be installed in accordance with the operating and installation requirements of Overvoltage Category II and Pollution Degree 2 (as defined by IEC 664). It must be fitted in a suitable enclosure which is accessible to qualified personnel only. See page 39 for panel cut-out dimensions.

When using an AC supply to power the unit a suitable fuse must be used. The recommended fuse is type - S504-250mA manufactured by Bussmann.

Fuse details: Antisurge 250mA, Rating 250VAC, Breaking capacity 35A @250VAC, UL recognised (file no E75865), complies with IEC127.

The relay output circuits must be fitted with fuses suitable for the voltage and current being switched.

All conductors carrying hazardous voltage should have external switching or disconnect mechanisms fitted which provide at least 3mm of contact separation in all poles.

Failure to install or operate the unit in accordance with the above requirements may result in the electrical safety of the unit being impaired.

Maintenance

Ensure that all power sources to the unit are isolated prior to maintenance, inspection or cleaning.

There are no user serviceable parts inside this unit. Under no circumstances should the case be opened.

All external wiring connections should be inspected at regular intervals. Any damaged wiring should be replaced and any loose connections should be retightened.

Cleaning should be carried out using a dry cloth to wipe the casing of the unit.
