Operation Manual no. BP/IO/21/16 ed. 5.2.1
11.4 Inspections and maintenance principles
It is recommended to perform quarterly inspections of safety device functionality and electric
connections correctness. Check the security settings according to the legal acts applicable in
a specific country.
In case of need the settings may be adjusted in accordance with the protected network.
11.5 Repairs
Repairs of type ER 100ims relay security by users are prohibited. BARTEC reserves the ex-
clusive right to remanufacture and repair type ER 100ims protection. Any design changes made
by the user of the ER 100ims relay will void the warranty and the user will be liable for any con-
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.
