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.

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

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.

Lighting control in a production room

Task

To automatically turn on the lighting fixtures in a production room
during production hours. The lights should turn on and off gradually
in response to changes in the daylight level. It must be possible to
turn the switch for the individual lighting stages on and off manually
at any time. Faults in the lighting system should be signaled by a
flashing light.

Overview drawing

Connection to the busbar system

Phase 1:
Every 1st, 4th, 7th, and 10th neon light.
Activated via contactor K1.
Enabled via daylight control switch B1.

Phase 2:
Every 2nd, 5th, 8th, and 11th neon light.
Activated via contactor K2.
Enabled via daylight control switch B2.

Phase 3:
Every 3rd, 6th, 9th, and 12th neon light.
Activated via contactor K3.
Enabled via daylight control switch B3.

Lighting stages

Stage 0:
All the lights are off.

Stage 1:
Every third light is on. Contact B1 is closed.

Stage 2:
Every third light is off. Contacts B1 and B2 are closed.

Stage 3:
All the lights are on. Contacts B1, B2, and B3 are closed.

Manual operation

It must be possible to switch the individual lighting stages
atlightswitches S1 through S3.

Use of the manual function is signaled by indicator lights
H1throughH3.

Figure 23. Overview

Operating description

Three light fixtures, each with 12 fluorescent lights, are suspended
from a busbar system. The lighting is on from 6:00 a.m. to 5:30 p.m.
Monday through Friday and is varied according to the daylight level.
The switch-on times and the ON duration must be variable to suit
requirements.

Lighting stages

The use of three different switching stages guarantees the
necessary brightness, saves energy, and places a uniform load
onthe mains supply.

Failure of a busbar

The busbars are protected via miniature circuit breakers Q1 through
Q3 and are monitored by trip indicating auxiliary contacts. Faults are
signaled in the form of a group alarm via flashing indicator lightH4.

ote:N If the daylight control switches already have an ON-delay or OFF-delay,

these times should be set as low as possible (of the order of 1 second).
Alternatively, the ON-delayed timers T1 through T6 programmed in the
easyRelay (default value 60 seconds) can be changed to obtain the required
overall delay.

Booster pumps

Task

Two pumps provide the water supply for an installation. Their
operation is to be monitored. The two pumps are to be operated
alternately to prevent excessive wear. The operating status and
the faults within the installation are to be signaled by two indicator
lights. It must be possible to select the pressure-related switching
points for activating the pumps as required.

Overview drawing

Faults

Electrical failure of a pump motor is detected by the trip-indicating
auxiliary contacts for the motor-protective circuit breaker Q1 and Q2.
The pump that is still in working order will be activated. If one of
the pumps is mechanically defective, the resulting drop in pressure
will be detected, and the other pump will be activated after time T4
has elapsed. Both fault types are signaled by the flashing indicator
light H1 or H2. When both pumps are electrically defective, indicator
lights H1 and H2 will flash simultaneously.

Low pressure

The system is monitored for low pressure, which is signaled
by indicator lights H1 and H2 that flash alternately after time T5
has elapsed. It must be possible to set the low pressure limit on
the easyRelay.

Acknowledgement

All fault messages are retained until they have been acknowledged
by pressing the S3 button.

Maintenance

It must be possible to directly switch pump P1 using key switch S1
and pump P2 using key switch S2.

Figure 30. Overview

Operating description

Pumping operation

The pumping station provides the water supply for an installation. It
must also ensure that the pressure does not fall below a specified
minimum level. There are two booster pumps—P1 and P2. If the
pressure is too low, one of the pumps is activated via pressure
sensor B1. To ensure that the two pumps are subject to equal use
and wear, they are run alternately for 48-hour periods. Two indicator
lights, H1 and H2, signal which of the two pumps is in use. If the
easyRelay is disconnected from the power supply, the operating
hours count will start again, and pump 1 will be activated first.

To enable the pumps to change over after a shorter or longer
operating period, counters C1 and C2 should be set to new
comparison values using the following formula:

Desired changeover time in hours x 60 = comparison value.

Default: 48 hours x 60 = 2880.

Access monitoring for a parking garage

Task

To monitor the occupancy of a company parking garage. Cars can
enter the garage provided that there are still some spaces available.
Access is controlled by a barrier system. The occupancy of the
garage is signaled by a “Full/Empty” display.

Overview drawing

Faults

A fault in the barrier system, which is signaled via make contact S1,
is displayed by flashing indicator light H1 in the garage attendant’s
booth.

Maintenance

The barrier can be opened by pressing the P2 function button
(Uparrow) on the easyRelay.

Figure 43. Overview

Operating description

Entry and exit

Access to the garage is monitored by a swipe card reader. If the
card is valid, contact S3 is closed briefly. When a vehicle leaves
the garage, contact S2 is closed via an induction loop embedded
in the ground. A display panel with the message “Full” or “Spaces
free” at the point of entry should indicate whether there are still
parking spaces available. If voltage is present at signal input K2, the
display panel should read “Full”, otherwise it should read “Spaces
free”. The barrier opens when a voltage pulse is applied to K1 for
2 seconds, and it closes automatically when a vehicle has passed
through or after a set time has elapsed.

Counting the vehicles

Incoming and outgoing vehicles should be counted by the easyRelay.
The maximum number of vehicles that can be parked can be set
on the easyRelay. Vehicles may enter if there are parking spaces
available. The counter can be reset to zero via the key switch S5 in
order to establish a baseline.

Manual operation

The garage attendant should be able to open the barrier at any time
using button S4, regardless of whether the garage is full or not.

Time-controlled lighting system

Task

To activate the lighting in rarely visited rooms in a library only
whenturned on by the user in order to save energy. The user
mayselect how long he/she wants the lights to remain on. It should
alsobe possible to switch the lights on and off permanently at a
central switch.

Overview drawing

Figure 47. Overview

Operating description

The four groups of lights (H1 through H4) in a library should only
beswitched on at a reader’s request. Two flush-mounted buttons
(S1through S8) are provided for this purpose at the end of a
shelving area. Ifthe reader presses the button briefly, the light will
come on for just 5 minutes. More pressure on the button will light
the area for a half-hour period. All the lights can be turned on and off
for cleaning via the central flush-mounted S9 button.

Perimeter advertising in a stadium

Task

The time-dependent control of four advertising panels, each with
three sides. Each side is to be visible for 30 seconds, after which
thenext side is to be turned to the front.

Overview drawing

Figure 61. Overview

Operating description

Start

Start/Stop button S5 is used to start the procedure for all four panel
fixture electrical strips. The visible advertising panel is on view for a
variable time (controlled via T1 through T4). It should be possible to
stop the entire procedure by pressing the S5 button again.

Rotation

Once the set time has elapsed, the motor (M1 through M4)
associated with the strip must start automatically. The strip rotates
to display the next advertising panel. Once the advertising panel
is in the correct position, this is signaled via the corresponding
limit switch (S1 through S4) and the motor is turned off. To enable
the strip to leave the limit switch position, disconnection must be
bypassed, again fora variable time (controlled via T5 through T8),
when the rotation procedure starts.

Testing and maintenance

It must be possible to activate the rotation procedure manually in
order to be able to test the individual strips during installation and
assembly and to replace the advertising panels. The cursor buttons
P1 through P4 on the easyRelay are used to activate a single turn for
each individual strip, and button S6 activates a single turn ofall the
strips together.

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

simultaneously to change to the Special menu.

to an underground garage. The door should open on request and
then close automatically after a set time. It should also be possible
to close the door upon request. The door is locked at certain times
of the day and certain days of the week. The limit switches and
mechanical operation of the door should be constantly monitored.

Operating description

Opening the rolling door

The rolling door can be opened from outside via a swipe card reader
and/or key switch S6. Contact K1 closes briefly once the swipe
card has been checked. It should be possible to lock the entrance
atcertain, variable times of the day and on certain days of the week

1); although it should always be possible to open the door using

(
key switch S5.

The door must be opened using pull switch S7 in order to leave
the garage.

Security

Door closing should be indicated by a brief audible signal (H3).
At the same time, red warning lights H1 and H2 light up at the
entrance and the exit. If there is a person, a vehicle, or another
object under the door while it is closing, the procedure will be
stopped or prevented via the contact in the safety bar (K2) and/or
the light barrier (K3). The door will either immediately open fully or
will remain open. If the safety bar is triggered, there is an audible
signal, and warning lights H1 and H2 light up.

The “Open door” function is disabled by the safety bar when the
door is closed (limit switches actuated) in order to prevent break-in
and vandalism.

The contact bar can be tested by triggering the alarm while the door
is open.

Pressing the emergency stop button stops all movement of the door.
Warning lights H1 and H2 will start to flash, and the audible signal
will start.

If the door is closed, the alarm cannot be triggered via the
emergency stop button. The “Open door” command must be given
to start the flashing lights and the audible signal in order to indicate
that the emergency stop button has been pressed.

Break contacts should be used for the emergency stop, safety bar,
and limit switch functions. The emergency stop button and the
safety bar must be wired as shown in Figure 67. This will guarantee
that the opening and closing procedure during an emergency stop,
and the door closing procedure when the safety bar is tripped, work
independently of the electronic circuit.

The following standards must be observed:

DIN EN 60 335-1 (VDE 0700 part 1)

DIN 57 700-238 (VDE 0700 part 238)

German Workplace Directive ASR 11/1-5ZH1/494
and ZH1/580.1 Safety Rules

Faults

Defective limit switches S1 and S2 (door closed S1/door openedS2)
and mechanical faults in the door must be detected. If a limit switch
is not working correctly, the drive should be shut down after a
variable time (T1 and T2) and warning lights H1 and H2 should start
to flash. The message can be cleared by pressing and resetting
emergency stop button S8. If emergency stop button S8 is pressed,
the warning lights should light up and a continuous audible signal
should start.

Closing the rolling door

Once a car has driven into the garage, the driver can close the door
manually via pull switch S7. If the driver does not use the pull switch,
the door will automatically close after a set time (T3). The door can
be opened and closed manually using the S4 and S5 buttons in the
control room.
