4 Intended use
Annex 3 to the OBAC 06 ATEX 059U certificate introduces a number of changes in the struc-
ture of ER 100ims leakage protection, which are designed to adapt to the current standards and
to change the method for processing the measurement signal. In addition, two variants (with and
without reset button) were replaced with one universal design. The manual reset function is ac-
tivated by means of the switch on the front of the unit. In this way, backward compatibility has
been maintained. The new version replaces previous versions of the device.
The ER 100ims type safety device is used to control the insulation state in insulated low
voltage electricity networks. Depending on the method of safety device connection to the con-
trolled network it may fulfil the following functions:
• Central leakage protection of three-phase alternating voltage network. In this case it is
preferable to connect the device through three chokes which ED 100i are connected with
one end to three phases of the network and with second end are connected in one point
creating „artificial zero” layout to which the measuring relay ER 100ims of the protection is
connected or directly to the N terminal of the transformer. It is possible to connect by one
choke connected at one end to the neutral point of the transformer (alternative connection).
• Central leakage safety device of a single phase voltage network. In this case it is preferable
to connect the device through two ED 100i chokes are connected by one end to phase
conductors of the network and by the other end are connected in one point, to which the
measuring relay ER 100ims of the safety device is connected or directly to the N terminal of
the transformer. It is possible to connect by one choke connected at one end to the neutral
point of the transformer (alternative connection).
• Interlocking leakage safety device in three- and single phase networks.
The measuring circuit of the measuring relay ER 100ims can work with the network controlled
only through chokes ED 100i or ED 100.
The following functions are fulfilled in the applications specified:
• Signalling and/or disconnecting at deterioration of the insulation state below the preset ref-
erence value, at the same time a controlled dropout time relay is released, which by its
contacts signals the operation and/or disconnects a circuit breaker or relay.
• Measurement and indication of the insulation state, where the spark-proof analogue input
may be connected with a spark-proof voltage indicator (0÷10 V) rescaled to the insulation
resistance reading, e.g. ER 100ws and/or spark-proof voltage transducer to another ana-
logue signal to transmit this information to other control and monitoring systems.
A non-spark-proof circuit consists of relay contacts and coil and also of safety device power
supply. The analogue output may be connected to spark-proof circuits of the ia protection level
(e.g. ER 100ws or spark-proof signal separator), while its measuring circuit, through the system
of ER 100i chokes, sends a spark-proof signal of ia protection level to the controlled network.
WARNING: For connecting the ER 100ims in place of the previous version without reset
button, terminals connection of the device remains unchanged. In the case of installing
the ER 100ims in place of the previous version with reset button, change the connections
of the terminals (tab. 1).

RESTRICTION: The device is designed to work in networks of alternating current with
a nominal frequency of 50Hz. Due to its structure of working principle (measuring DC),
the device CANNOT BE installed within the networks with receivers transforming AC
power into DC power directly, without additional separating transformer. It relates mainly
to rectifiers and receivers with DC intermediary circuits of inverters supplied directly from
the protected network.

(a) Front of the device
(b) Terminal layout
Figure 1: Protection ER 100ims
All electronic components are placed on two printed circuits in an ME 35 UT enclosure moun-
ted on a TS35 bus. Terminals (terminals 1, 2, 3, 7, 8, 9) of spark-proof circuits are located on
one side of the enclosure, while the power supply (terminals 19, 20) and non-spark-proof outputs
(terminals 16, 17, 18, 22, 23, 24), resetting the response state (terminals 20, 21) are located on
the opposite side. Such arrangement ensures proper separation between the spark-proof and
non-spark-proof sides.
The measuring circuit consists of one to three ED100i chokes waterproofed by a fill in a plastic
enclosure, bolted to the circuit board or it is made by direct connection to the neutral point of the
transformer. The relay and appropriate connection of measuring chokes make one inseparable
whole.
8.2 Electrical equipment
8.2.1 Scheme of connections
The ER 100ims safety device is connected to the power supply through terminals 19, 20 of
the connection port. An integrated pulse power supply with a separating transformer and a spark-
proof barrier feeds a spark-safe voltage to electronic components and to the measuring circuit,
which through terminals 1 and 2 is connected to the controlled network. The output relay is
activated at properly operating network and drops out in the event of disturbance. It has two
contacts with terminals 16, 17, 18 and 22, 23, 24. A spark-proof analogue measuring output is
allocated to terminals (3) 9, 8. A spark-proof measuring instrument may be connected to the
aforementioned terminals, e.g. resistance indicator ER 100ws or spark-proof signal separator to
work with another control or transmission system. As standard, terminals 3 and 9 are internally
connected. For „/J” variant, terminals 3 and 9 should be connected from the outside of the unit. It
ER 100ims Page 11

Operation Manual no. BP/IO/21/16 ed. 5.2.1
Figure 2: Implementation of the warning signal
is possible to control the executive stage from the other device, which allows for additional warning
signal (Fig. 2). Resetting of the fault state is accomplished by shorting the terminals 20 and 21.
8.2.2 Principle of operation
The ER 100ims works by measuring the resistance between terminals 1 and 2. When the
measured resistance falls below the value set with the potentiometer on the front of the device,
the output relay is deactivated. If the automatic reset function is activated after the resistance has
been increased, the relay is switched on again. When this function is inactive, it must be reset
using the RESET button on the front of the unit or by shorting the terminals 20 and 21. The blue
OK LED indicates the correct insulation status. While, the red ERR LED indicates the latching
information of the leakage fault state.
Between terminals 8 and 9 may be connected to external spark-proof devices (ia) of total
internal resistance ≥ 100 kΩ, i.e.:
– Resistance indicator, e.g. ER 100ws.
– Spark-proof separator for work with other systems.
8.2.3 Additional equipment
For single- or three-phase coupling of the safety device with the insulated controlled network
two or three inviolable ED 100i or ED 100 type coupling chokes are necessary to create artificial
zero point or by directly or with single choke to the neutral point of the transformer. The ED 100i
choke was made by winding a high-inductance coil on one core in a filled plastic encapsulation.
Possible connections are shown in Figure 4 and 5.
The ER 100ims safety device may operate with a spark-proof resistance indicator ER 100ws,
which is optional equipment.
9 Resistance indicator ER 100ws
Resistance indicator ER 100ws is a spark-proof device connected and supplied from the spark-
proof part of ER 100ims relay. It consists of a measuring circuit interpreting the measuring signal
received from ER 100ims and displays the result in the form of insulation resistance on the display
installed. The power supply is drawn from ER 100ims and it is 18V DC ± 5%. The resistance
indicator draws a current below 1,5mA.

The indicator has a switch that is suited to subtract from the displayed value typical resistance
for used ED 100i chokes connection. When connecting 2 or 3 chokes, set the switch to „∼3”.
If the connection is applied through one choke, set the switch to „∼1”. Setting the switch in the
middle position disables this function

11 Service and operation
11.1 Installation
The ER 100ims safety device is connected to the power supply through terminals 19, 20. The
measuring circuit is connected to the controlled network through terminals 1 and 2. For single- or
three-phase coupling of the safety device with the network one, two or three inviolable ED 100i
or ED 100 type coupling chokes are necessary.
The output relay is activated at properly operating network and drops out in the event of dis-
turbance. It has two changeover contacts with terminals 16, 17, 18 and 22, 23, 24. Spark-proof
measuring output is allocated to terminals (3) 9, 8. The above terminals may be connected to
a spark-proof resistance indicator, e.g. ER 100ws and/or spark-proof signal separator for opera-
tion with another control or transmission system.
Relay operating as interlocking protection should be disconnected from protected outflow
when network voltage is switched on. Protection should be reconnected to the protected out-
flow after switching off the voltage.
11.2 Electric shock protection
Due to the fact that dangerous voltages may occur on the protection’s terminals the safety
regula-tions and general rules of proceeding in such conditions should be observed.
11.3 Storage and transport conditions
Protection ER 100ims, indicator ER 100ws and chokes ED 100i should be stored in closed
warehouses at temperatures −20…+40°C and at relative humidity up to 75%, free from harmful
vapours and gases.
The device should be transported using covered means of transport in the factory packaging
that prevents damage at ambient temperature of −20…+40°C and relative humidity of up to 93%.
During transport, secure the load against shifting.

sequential losses.
11.6 Disposal
After passing of the operational period the device must be disposed in accordance with ap-
plicable regulations regarding the environment protection.
In case when user does not have an appropriate knowledge in this scope he should obtain
information from a proper office of local authorities.
Electrical or electronic equipment contains components, materials or components that should
be removed from waste equipment and which may have potentially negative effects on the envir-
onment and human health.
11.7 PN-G-42040 setting resistance
The earth leakage central trip shall feature a system for testing its operating performance and
connection to the operating earth. This is done by simulating a single-line insulation failure of the
mains with a breakdown resistance equal to 0.8 times the setting resistance and a tolerance of
−20%. The setting resistance values are listed in Tables 6a and 6b.
11.8 Central/interlocking trip settings
Wire the measuring leads of the trip module to the monitored mains in one of the configurations
shown in Fig. 4 and 5. The alternative wiring configuration of the central trip will extend the trip
trigger delay.
Next, decade resistor should be connected between terminal 1 of the protection and any
phase. Set minimum value of operation resistance (2kΩ) using potentiometer on the protection.
Set proper value of operation resistance acc. to the tables 6a and 6b on decade resistor.
Switch on supply voltage of the protection (if necessary unlock central interlocking using but-
ton) and gradually increase resistance value on potentiometer of the protection until executory
relay is activated. Leave potentiometer of the protection in this position.
Next, increase significantly set value of resistance of decade resistor, e.g. to 100kΩ. When
central protection is set it should be unlocked with button. Decrease set value of resistance of
decade resistor until activation of the executory relay to check the set value of operation resist-
ance. Read out and/or measure value of resistance on decade resistor. Its value cannot differ by
more than ±20% with respect to this given in the tables of operation resistance.
In case of system protected by ER 100ims the terminal no. 1 of the protection should be
connected to protective terminal PE.

It is also possibile to set the device by direct connection of the decade resistance to terminals
1 and 2 of the protection:
When configuring the earth leakage central trip settings (Fig. 4)), remember that alternative
(injected) resistance of the wired chokes or resistors. The value of this resistance depends on the
wiring configuration of the monitored mains. The resistance of a single ED 100i choke is 7,1-7,5
kΩ ± 20%. Example: the wiring configuration shown in Fig. 4e features a parallel connection of
three resistors (and where constant component transformer provides the short-circuit); the wiring
configuration shown in Fig. 4g provides a single functional choke (the mains phases are not
interconnected).
For a interlocking trip (see Fig. 5), two scenarios can exist. First, no load is connected, as
shown in Fig. 5a and 5b. In this scenario the mains phases are not interconnected and the
injected resistance is equal to the resistance of a single choke. Second, a load is connected to
the outlet line, as shown in Fig 5c and 5d. Here, the phases are shorted (via a motor for the
constant component) and the injected resistance is equal to the resistance of the chokes wired in
parallel.
To determine the injection resistance for the central and earth leakage trip with loads other
than an electric motors, each case must be considered individually.
WARNING: Only one earth leakage trip can be operated in the given section of the supply
mains. The interlocking trips must be isolated from the monitored mains when the outlet
is online – the interlocking trips must not be online with the supply voltage connected to
the load.
11.9 Setting of indication of ER 100ws display
The indicator is factory calibrated and displays the correct value of the measured resistance.
However, if for some reason it is necessary to correct the indicated value, it can be done with the
potentiometer built into the indicator.

Indications should be set only after completing settings executed according to the point 11.8.
Settings should be made when voltage of network controlled by relay is switched on.
When relay ER 100ims is already correctly set, then resistance should be connected (e.g. dec-
ade resistor) simulating ground fault with value close to resistance of operation but slightly higher
in a way preventing operation of the relay. Then using potentiometer available near the socket of
ER 100ws display indications of values presented on the LCD display should be corrected to the
value equal to the value of connected simulated resistance of ground fault.
If replacement on one device from previously calibrated pair ER 100ims and ER 100ws is
necessary then displayed value of resistance should be rechecked and corrected if necessary.
