In RUN mode EZ continuously processes a stored circuit diagram until you select STOP or disconnect the power. The circuit diagram, parameters and the EZ settings are retained in the event of a power failure. All you will have to do is reset the real-time clock after the back-up time has elapsed. Circuit diagram entry is only possible in STOP mode.

The last coil in the circuit diagram determines the status of the relay. J When controlling a contactor or relay, the control coil is only present once. If you are creating parallel circuits, use Set, Reset as a coil function.

EZ500_700.book Page 91 Tuesday, May 3, 2005 5:15 PM Working with contacts and relays Contactor function with negated result (inverse contactor function) Å The output signal is simply an inversion of the input signal; the relay operates like a contactor with contacts that have been negated. If the coil is triggered with the 1 state, the coil switches its make contacts to the 0 state.

The counter signals are transferred directly from the digital inputs I3 and I4 to the counters. A frequency counter measures the actual value and does not measure a direction. You only integrate a frequency counter into your circuit in the form of a contact and enable coil.

EZ provides two high-speed up/down counters C13 and C14 for use as required. The high-speed counter inputs are permanently connected to the digital inputs I1 and I2. These counter relays allow you to count events independently of the cycle time. The high-speed counters allow you to enter an upper threshold value as a comparison value.

The speed with which a contactor switches in this case depends on the components used, and ranges from 15 to 40 ms for relay pick-up and drop-out.
PAGE 236
EZ500_700.book Page 232 Tuesday, May 3, 2005 5:15 PM Inside EZ The fifth segment is outside the circuit diagram and EZ uses it to establish contact to the “outside world”: The output relays Q1 to Q... are switched and inputs I1 to I.. are read again. EZ also copies all the new switching states to the status image register. EZ only uses this status image for one cycle.

This is the circuit diagram of a self-latching circuit. If I1 and I2 are closed, the switching state of relay coil ÄQ1 is latched via contact Q1. • 1st cycle: Inputs I1 and I2 are switched on. Coil ÄQ1 picks up. • Contact Q1 remains switched off since EZ evaluates from left to right.

EZ500_700.book Page 234 Tuesday, May 3, 2005 5:15 PM Inside EZ Delay times for inputs and outputs The time from reading the inputs and outputs to switching contacts in the circuit diagram can be set in EZ via the delay time. This function is useful, for example, in order to ensure a clean switching signal despite contact bounce.
PAGE 239
EZ500_700.book Page 235 Tuesday, May 3, 2005 5:15 PM Delay times for inputs and outputs An input signal S1 must therefore be 15 V or 8 V (EZ-DA) for at least 20 ms on the input terminal before the switch contact will change from 0 to 1 (range A). If applicable, this time must also include the cycle time (range B) since EZ does not detect the signal until the start of a cycle. The same time delay (range C) applies when the signal drops out from 1 to 0.

If the debounce delay is switched off, the delay time is reduced. • On delay 20 ms (16.6 ms) • Off delay for I1 to I6 and I9 to I12: 20 ms (16.6 ms) • Off delay for I7 and I8: 100 ms (100 ms) with EZ-AB, EZ-AC S1 Figure 87: 1 1 A B On and off delays EZ switches the contact as soon as it detects a pulse (A).

EZ500_700.book Page 248 Tuesday, May 3, 2005 5:15 PM Inside EZ EZSoft EZSoft is a PC program with which you can create, store, test (simulate) and manage EZ circuit diagrams. J You should only transfer data between the PC and EZ using the special PC interface cable, which is available as an optional accessory EZ-PC-CAB. DANGER of electric shock with EZ-AC units! Only the EZ-PC CAB cable will guarantee reliable electrical isolation from the interface voltage.

J Card mode operation is not possible when using a standalone display/operating unit. The interface can only be used once. The EZD-80 (IP65 display unit), EZD-80-B (IP65 display/ operating unit) with the EZD-CP4-500 power supply/ communication unit are currently available for use as standalone display/operating units.

EZ500_700.book Page 277 Tuesday, May 3, 2005 5:15 PM Glossary Analog input The device EZ-AB, EZ-DA and EZ-DC are provided with the two (EZ500) and four (EZ700) analog inputs I7, I8 and I11,I12. The input voltage range is 0 V to 10 V. The measuring data is evaluated with the integrated function relays. Circuit diagram elements As in conventional wiring, the circuit diagram is made up of circuit elements. These include input, output and marker relays, plus function relays and P buttons.
PAGE 282
EZ500_700.book Page 278 Tuesday, May 3, 2005 5:15 PM Glossary Impulse relay An impulse relay is a relay which changes its switching state and retains its new state (latched) when a voltage is applied to the relay coil for a short time. Input The inputs are used to connect up external contacts. In the circuit diagram, inputs are evaluated via contacts I1 to I12 and R1 to R12. EZ-AB, EZ-DA and EZ-DC can also receive analog data via the inputs I7, I8 and I11, I 12.

EZ500_700.book Page 279 Tuesday, May 3, 2005 5:15 PM Operating buttons EZ has eight operating buttons. These are used to select menu functions and create circuit diagrams. The large round button in the middle is used to move the cursor. DEL, ALT, ESC and OK all perform additional functions. Output You can connect various loads to the four EZ outputs, such as contactors, lamps and motors. In the EZ circuit diagram the outputs are controlled via the corresponding output relay coils Q1 to Q8 or S1 to S8.
