Showroom and store window lighting

Task

To automatically switch the showroom lights, store window lighting,
and external advertising display for a retail store on or off. The on/off
function must take into account the day of the week, the time, and
a daylight control switch. The connection times for the store window
lighting can be set as required. It must also be possible to switch
all the lights on and off manually. The showroom and store window
lighting must turn on in the event of an alarm.

Time switch 3
1:55 a.m. to 6:35 p.m.

Sat 8:55 a.m. to 2:05 p.m.

The flush-mounted switches S1, S2, and S3 can be used to activate
the showroom lighting outside the programmed times.

In the event of an alarm, the showroom and store window lights are
turned on by contact S6.

External advertising display

Mon–Sun 6:00 a.m. to 11:00 p.m.
Time switch 1

The daylight control switch causes the advertising display to turn off
as the light level rises and to turn on at dusk.

It must also be possible to manually turn the advertising display on
and off at any time. The P2 (Up arrow) and P4 (Down arrow) function
buttons on the easyRelay are used for this purpose.

ote:N The P buttons are activated in the Special system menu. Press ALT

and DEL simultaneously to change to the Special menu. See also the User
Manual MN05013003E.

Store window lighting

Mon–Fri 8:00 a.m. to 10:00 p.m.
Time switch 2

Sat 8:00 a.m. to 11:00 p.m.

Sun 10:00 a.m. to 10:00 p.m.

The store window lighting is also controlled by the daylight control
switch. It is turned off as the light level rises and is turned on when
it starts to get dark.

The S5 button is used to turn the store window lighting on and off
manually outside the programmed times.

In the event of an alarm, potential-free contact S6 in the alarm
system turns the store window lighting on.

Once time switch 2 has been enabled, it can be used to change
the on/off times, even if a password was activated up in the Special
menu. The time switch is enabled by programming the “+” symbol.

Floor lighting

Task

To enable the corridor lights on each floor of a multi-story building
to be switched on and off at various flush-mounted switches. In
parallel, there should also be a central switch from which all the
lights can be turned on and off. In the event of a fire, it must be
possible to turn on all the corridor lights. To save energy, the corridor
lights should be turned off altogether at certain times.

If necessary, for example, for cleaning, the corridor lights on every
floor can be turned on at switch S13 and turned off at switch
S14 in the maintenance personnel’s quarters or the building
superintendent’s room.

In the event of a fire, contact K1 in the fire alarm system turns on all
the corridor lights.

To save energy, all corridor lights are turned off at 6:30 p.m. Monday
through Friday and at 2:30 p.m. Saturday.

Belt sequence control for three conveyor
belts with motor monitoring

Task

To start up and shut down three conveyor belts at different times.
There are to be three operating modes “Staggered start-up”,
“Staggered shut-down”, and “Fast stop”. The motor-protective circuit
breakers in the belt drives should be monitored; if a circuit breaker
trips, the conveyor system should stop in a controlled manner.
Thefault should also be signaled by a flashing light.

Overview drawing

Belt 1

Belt 2

10

Motor failure

If a drive motor fails, the trip-indicating auxiliary contact (PKZ) opens.
The fault is signaled via the flashing light and automatically triggers
the STOP function. This means that in the event of a fault, any belts
downstream of the defective drive run at no-load for 5 seconds
before they are turned off. Any belts upstream of the defective drive
are turned off immediately.

Figure 10. Overview

Operating description

The three conveyor belts in a bulk material handling installation have
to be started up and shut down at different times in order to ensure
that the materials are transported safely and without interruption.

Startup

When START button S1 is pressed, the belts start up at 5-second
intervals (this interval is permanently programmed and cannot be
changed). Belt 3 starts up first.

Shutdown

When STOP button S2 is pressed, the belts stop in reverse order,
i.e., starting from belt 1. This guarantees that the belts are running
at no-load when they are restarted, thus avoiding heavy starting with
a loaded belt.

When the button is pressed, 5 seconds elapse before belt 1 is shut
down. The subsequent belts turn off again after a 5-second delay. It
must be possible to change the time via the easyRelay. To do this,
the “+” must be set when the function block is programmed.

“Fast stop” button S3 turns off all three belts without a timedelay.

Greenhouse temperature and
ventilationcontrol

Task

To automatically open and close the roof lights of a greenhouse in
order to adjust the ventilation and temperature. Warm air should
beblown in via the heating system when the temperature drops
below a certain level. The drive motors for the fans and the roof
lights must be monitored for faults, which should also be signaled
bya flashing light.

Overview drawing

Warm air supply

When the temperature in the greenhouse falls below a certain level,
the fan motor M2 is automatically activated to blow in warm air. The
motor is switched off again when the temperature returns to the
desired level.

Motor failure

If M1 or M2 fails, the contact of the corresponding trip-indicating
auxiliary contact Q1 or Q2 opens. The fault is signaled via the
flashing light H1 for both motors.

Continuous ventilation

Key switch S1 is used to turn off the automatic temperature control
and select “Continuous ventilation”. It may be necessary to first
close the roof lights and then open them again in order to use
thisfunction.

It should be possible to enter the motor run time T2, which
determines how far the roof light is opened, directly on the
easyRelay.

The roof lights can be opened as far as the end position. The default
for T2 is 4 seconds.

Manual operation

For maintenance and repairs, the windows can be opened via the
P2button (Up arrow) and closed via the P4 button (Down arrow).

ote:N The P buttons are activated in the Special menu. Press ALT and DEL

simultaneously to change to the Special menu. See also the User Manual
MN05013003E.

Figure 17. Overview

Operating description

The greenhouse is also used as a display and sales area. The roof
lights are opened for ventilation and are closed again depending
on the temperature. The “Open window” and “Close window”
switching points are programmed via the easyRelay. The voltage
output of temperature sensor B1 supplies the necessary comparison
value. The following example demonstrates how the switching points
are determined or calculated.

Ventilation control

All the roof lights are activated by a three-phase AC motor M1 with
a reversing contactor circuit. The end positions are detected by limit
switch S2 (open) and S3 (closed). The motor switches off when the
limit switch is reached.

value to avoid having to repeatedly turn ON and OFF when the
comparison value is reached.

t

This gives the following switching points
in the comparator blocks:

t Open window

ON = 6.8V
OFF = 6.6V

t Close window

ON = 6.3V
OFF = 6.5V

t Heat

ON = 6.0V
OFF = 6.2V

List of operands

A1 Comparator, Open window ON

A2 Comparator, Open window OFF

A3 Comparator, Close window ON

A4 Comparator, Close window OFF

A5 Comparator, Heat ON

A6 Comparator, Heat OFF

I1 Input, key switch for continuous ventilation

I2 Input, Open limit switch

I3 Input, Closed limit switch

I4 Input, window drive motor trip-indicating auxiliary contact.
Input, fan motor trip-indicating auxiliary contact

I8 Input, comparative voltage of temperature sensor
