In order to configure the call point using a personal computer, Lectus Modbus OPC/DDE server
(ver. 3.9 and above, www.lectussoft.com), Modbus Poll (v.5.0.1 and above,
www.modbustools.com) software or a specialized application ‘Configuration tool IP535-07ea-RS’
(www.eridan.ru) can be used.
Any function of Modbus RTU announced for the call point can be deemed realized if a
corresponding variable can be read/recorded using Lectus Modbus OPC/DDE server (ver. 3.9) or
Modbus Poll (v.5.0.1 and above) software.
The call point provides support of the following operation modes: standby mode, “Activated’
mode, ‘Acknowledgement’ mode, ‘Failure’ mode.
The call point operates in standby mode when the driving element is installed, the activation
signal is reset and there is no failures.
The call point generates ‘Activated’ alarm notification when the driving element is pulled out.
The call point transfers ‘Activated’ message to FACP by means of opening or closing of the relay
R1 contacts (adjustment of the relay off-position is carried out during the device configuring).
When the ‘Activation registration’ function is active, resetting of the call point from ‘Activated’
mode to standby mode is possible only with the driving element installed after receiving a ‘Device
reboot’ or ‘Registered events reset’ command from the control device or when the call point is
powered down. In order to comply with GOST R 53325-2012 and when operating the call point in
the territory of Russia, the ‘Activation registration’ function must be activated.
When ‘Automatic recovery’ mode is activated, reset of the call point from ‘Activated’ mode
can be carried out minimum 10 seconds after such activation.

The acknowledgement function (activation acknowledgement issued by the panel) can be
activated in the call point.
The call point generates ‘Fault’ notification in case of automatic detection of a malfunction.
The call point transfers ‘Failure’ message to FACP by means of opening of the relay R2 contacts.
When operating with a top level controller, the call point uses the serial interface RS-485
(Modbus protocol, transfer mode RTU) for transfer of data related to its condition and other service
data. The call point supports operation via Modbus RTU protocol in driven device mode.
Description of Modbus RTU exchange protocol in provided in Annex B.

4.4. In order to activate the addressable call point IP535-07ea-RS (addressable remote start
device IP535-07ea-RS-START):
–connect the call point (device) to the power supply source and the RS-485 communication
line. If necessary, connect the actuating relays R1 and R2 of the call point (device). Operation of
the call point (device) should be controlled by means of operation of its internal indicator, relay
condition as well as its own status displayed in register 10 (see Annex B)
–pull out the driving element (for the IP535-07ea-RS-B or IP535-07ea-RS-START, shift the
protective element (8) thus breaking the removable element (3) and giving access to the driving
element (2), then pull out the driving element)
–this will cause the instrument to receive the ‘Activated’ signal from the call point (device);
it will display the corresponding message and will send back to the call point an acknowledgement
of successful signal receiving (if the acknowledgement function is active). Upon receiving of the
acknowledgement signal by the call point (device), its transition from standby mode to ‘Activated’
mode will be indicated by the red signal LED of the call point (device); the actuating relay R1 will
change its status
–return the driving element (2) to the initial position (for the IP535-07ea-RS-B or IP535-
07ea-RS-START, return the driving element (2) to the initial position; install the protective element
(8) fixing it with the removable element (3) from the scope of supply)
–the method of returning the call point from ‘Activated’ mode back to standby mode will
depend on the value of bit 0 ‘Activation registration’ in register 50 (see Annex B).
