Hazards identification
The cage nit is powered by 12VDC NiMH battery. It sho ld be taken to consider that
in a f lly charged battery d ring setting p might be done by accident shorting pins
which may ca se battery leakage, overheat and in a conseq ence may ca se inj ries
(s ch as b rns). The battery sho ld be charged only by the original charger ŁAE-S3.
Used batteries sho ld not be thrown away in the trash. The cage nit sends once per
min te to the headframe nit control signal, accompanied by a beep. The PAK cable
has incorporated connection between pins 4 and 7 for a thorization higher speed. This
cable sho ld be installed in safe place for raise and lower with high speed.
Headframe nit is s pplied from 230 VAC network and sho ld be connected to a wall
o tlet with a protective pin (this applies to primary and reserve power s pply). The
casing of headframe nit is made of sheet steel, so it sho ld be gro nded. Opening the
ho sing is allowed only after disconnect from the power. The "

 " sign on the
inp t/o tp t block means that inside can be dangero s voltage from the shaft system.
Headframe nit sho ld be installed in safe place i.e. not in EX zone. Power- p seq ence
is as follows: first main power and second reserve power. In other case there might be
occ r an electrical arc on contacts of power s pply switch relay
1. Use and range of application
Device of wireless shaft communication ECHO-PG version EN1 is intended to use in
shaft sinking to communicate between crew in platform and hoist operator in mine shaft.
Whole communication system consists of two sets of components named as the headframe
unit and the cage unit. Communication between these units is realized by means of hoisting
ropes, which are carriers of the electromagnetic wave.
The basic advantages of this system are following:
- two-way semiduplex audio communication,
- sending remote control signals from platform to a hoist machine,
- receiving information signals from a hoist machine to platform.
The cage unit is made as intrinsically safe device group I, category M1.
The principle of working of this device is utilization rope as carrier to move electromagnetic
waves. Carrier is created by:
- guiderope and earth,
- additional rope and earth.
Electric continuity of such loop is the main condition of correct work of device.
Electromagnetic wave is generated to the loop and received from it by inductive couplers.
There are fixed two inductive couplers (transmitter and receiver) in headframe in such way,
that headrope crosses by their center. Over conveyance there are fixed another pair of
couplers. Headframe unit sends signal by inductive coupler (transmitter) to rope and cage unit
receive signals from rope by other inductive coupler (receiver). Communication from cage
unit to headframe unit is performed in the same way by pair of couplers fixed over
conveyance. Only one device can work in one loop, which means that one headframe unit can
only communicate with one cage unit. The device has four frequency version:
A, B, C, D thanks to which, it is possible to use four system in one shaft.

6. Description
Drawing no. 8PG.V1 shows overall structure a communication system in variant 1
with manipulator EPG. Drawing no. 8PG.V shows overall structure a communication
system in variant with additional signaling devices. System consists of two sets of
components: the headframe unit which is shown in drawing no. 8PG.0 and the cage unit
drawing no. 8PG.01. There are installed two inductive couplers in headframe in such way
that the rope passes through the center of couplers. One of them is transmitter and the second
one is receiver. The second pair of couplers is fitted over conveyance. Transmitting coupler
sends current signal, which flows through rope to the receiving coupler. The main condition
of proper work of system is existence of a closed loop for current flow (does not apply to
frequency version D). This loop is formed by headrope and platform. In case of existing
guiderope loop may be done by making connection between two such ropes or by connecting
to ground ends of guiderope. For frequency version D such loop is formed by headrope and
the capacitance headrope-shaft. Blok diagram of cage device is shown in drawing no.
8PG.01.0 . Blok diagram of headframe device is shown in drawing no. 8PG.0 .0 .
Transmitters of both devices emit continuously carrier frequencies. There are two carrier
frequencies at each system, which depend on version of devices. When both carrier
frequencies are present the device is switched to ready mode. Contacts NO or NC of the
circuits which will be connected to the headframe device inputs should be connected between
proper input and common terminal. Communication from a platform is realized by a cage
device. Communication from a bottom is performed by a manipulator EPG drawing no.
8PG.01.V1. In the case where using a manipulator is burdensome instead of it can be use the
additional signaling devices, what is shown in drawing no. 8PG.01.V . If the socket is
unconnected there will be emitted a continuous alarm.
6.1. A dio comm nication is realized in a semiduplex way. Cage device is continuously in
the receive mode when the unit is in ready mode and not transmitting. Voice communication
is done only from cage device after pressing and hold blue button PTT, platform has priority.
In headframe unit broadcast is done after pressing microphone foot switch.
6.2. Signal code is used to transmit the Code of Signals. After pressing yellow button CODE in
cage device, output relay P7 is turned on in headframe device if input no. (ACS) and input no. 7
(AP) in headframe device will be closed. After pressing yellow button CODE in manipulator or
after using additional signaling device, output relay P8 is turned on in headframe device if input no.
(ACS) and input no. 8 (AB) in headframe device will be closed. In cage device we should hear
bell if feedback microphone would be fastened near to signal bell as well as we should see green
led CCS if input no.1 (CCS) in headframe device will be connected to output of relays P7 and P8.
6.3. Signal alarm is send from cage device after pressing red button ALARM in cage device or
red button ALARM in manipulator. It is possible to hear alarm bell in cage device, for this purpose
should be closed input no. 3 (CA) in headframe device. This input activates feedback microphone
so it should be fastened near to alarm bell.

8. Maintenance
Before using any cage device it is recommended to charge the battery, using a charger
ŁAE-S3 CARBONEX company production. To do this, connect the plug of charger into the
battery socket in cage device or remove the battery from the cage device housing and put it on
the charger basket and then turn on the power of charger. Charging may take place only in
room without any danger vapours. Battery, on which there are traces of leakage should be
withdrawn by person of service and returned to the manufacturer. The battery may not have
dents. In the headframe device power-up sequence is as follows: first main power and second
reserve power. In other case there might be occur an electrical arc on contacts of power
supply switch relay. Cage device should not be at the same time, use the audio and control.
After pressing simultaneously two control buttons only one of them will be send. The foot
switch should be pushed only in time of audio transmission. Measurements of the installation
should be performed at least once a year.
Ind ctance of co pler SK should be measured in disconnected plug of cage unit.
During the measurements the headframe unit must be turned off.
