It is necessary to inspect the equipment at the time it is delivered to ensure that the relays have not been damaged during transport. If any defect is found, the transport company and FANOX should be informed immediately. If the relays are not for immediate use, they should be returned to their original packaging.
All electrical power sources should be removed before performing this operation to avoid the risk of electrical discharge. This product must be disposed of in a safe way. It should not be incinerated or brought into contact with water sources like rivers, lakes, etc… www.fanox.com SIAB_ENG_V1 6/81...

5.7. Test Menu The SIA-B equipment has a test menu that can be used to check the operation of the signalling components (LED indicators) and the outputs. It is important to point out that the operation of the outputs is not guaranteed if the test is performed with the battery.
5.8. Power supply The SIA-B equipment is designed to be self-powered using the cell current. Besides, depending on model it is possible to select apart from self-powered, an auxiliary supply (230 Vac, 110 Vac or 24 Vdc). It can also be supplied from a USB cable which goes directly till PC. The USB is plugged into the front communications port.
Striker activation The activation of the SIA-B trip output means that a capacitor has discharged on the output terminals. This discharge of energy is sufficient to activate a striker that mechanically acts on a mechanism to open the current circuit. The striker is connected directly to the SIA-B output, which supplies sufficient power to activate it (24 Vdc –...

7.2. Indicators The SIA-B front panel has two LED pilot lights to show if the equipment is ON (LED ON) and if there has been an alarm (LED ALARM). The LEDs are switched off when the equipment is not On, or when there is not an alarm, and they are switched on when some of those situations occur.
7.3. LCD and keypad The front of the SIA-B relay is fitted with an alphanumeric LCD screen, measuring 20x2. This screen provides the user with access to read information about the settings parameters, measurements, state and events. All of this information is arranged in a system of menus.

MODBUS RTU PROTOCOL This document describes the steps to follow to read and write data on the SIA-B relay, as per the ModBus/RTU protocol. This memory map is only valid for one piece of equipment and one version of the memory. The positions of existing objects in the memory remain fixed from one version to the next, but new objects will naturally have new addresses which will, in turn, remain fixed in future versions.

9.7. Front communications port To perform this test, connect a PC with the SICom software program to the SIA-B relay, and check that there are no communication errors. It is important to check communications port (COM) which is assign to USB.
It is recommended that the following safety measures are taken before starting up the facility for the first time, or after a trip event: FANOX recommends the use of the KITCOM accessory with a battery in the front port. This additional energy source allows the relay to be monitored and the trip to function without the need for self-power in any breakdown situation.
