GREISINGER EBUW 232 A (01) PDF MANUAL

The EBUW232A is inserted between the EASY BUS converter and the requesting device (MODEM, PC, etc.) using an adapter cable. The connection order is as follows:

EBW…/EB2000 ⇔ adapter cable (multiple cable outlet at EBUW-end) ⇔ EBUW232A ⇔ PC/Modem

If the device is used only as a protocol converter, no additional power supply is required, as it taps power from the RS232 voltages of the requesting device.

If the device is used for alarm supervision, an external power supply should be connected to the cable marked “Versorgung” (supply) because the power from the RS232 interface might not be sufficient. Note: When using devices with weak RS232 signals (e.g., some laptops), an external power supply might be necessary even when the device is used as a simple protocol converter.

The alarm output is available through the cable labeled “Alarmausgang” (alarm output) of the adapter cable.

The configuration of the EBUW232A is done using the MODKonfig software (Version ≥V1.9).

Follow these steps:

1. Click on the choice “prepare EASYBUS for remote operation or EBUW232A operation”.

2. Select the interface in the new window and click the button “check EASYBUS”.

3. The system will check all connected modules. If a correct EASYBUS is detected, the EBUW 232A will be shown with an “EBW” symbol.

4. Double-click on EBUW 232A: the configuration dialog will open. Choose the desired behavior and confirm with the OK button.

Important Note: If an EBB4out module is used, it must be connected during this check. If the assembly is changed (by adding or removing modules), the configuration must be performed again.

The EBUW232A scans one of the connected modules every 500ms and checks it for alarm conditions. Once all sensor modules are scanned, the alarm output will be set accordingly.

If a sensor module does not respond to the EBUW232A, 2 more attempts will be made. If it still does not respond, this is considered a valid alarm condition.

The behavior of the alarm output can be configured using the MODKonfig software.

When configured to “conducting in case of alarm”:

Output opened: No alarm – no module has an alarm condition or error.

Output conducting: Alarm – at least 1 module has a min-alarm, max-alarm, system error, or communication error.

When configured to “not conducting in case of alarm”:

Output conducting: No alarm – no module has an alarm condition or error.

Output opened: Alarm – at least 1 module has a min-alarm, max-alarm, system error, or communication error.

The EBUW232A scans one of the connected modules every 500ms and checks it for alarm conditions. When it reaches the switching module, the alarm states will be sent to the module, and the corresponding outputs of the switching module will be set. Note: The complete alarm state of all modules can only be sent to the EBB4Out after the first complete scan.

If a sensor module does not respond to the EBUW232A, 2 more attempts will be made. If it still does not respond, the alarm conditions communication error and collective alarm will be set.

The 4 different alarms indicated at the 4 relays of the EBB4out are:

When operating the EBB4out in combination with GSOFT40K, the GSOFT40K resets all modules during the ‘logger connect’. This results in a release of all relays with immediate reactivation of all relays. The correct state will be indicated again after the following complete scan.

1. Trouble-free operation and reliability of the device can only be guaranteed if it is not subjected to any climatic conditions other than those stated under “Specification”.

2. Before opening the device, disconnect it and its supply voltage source. Ensure all parts of the device are protected against direct touching when mounting and setting its connections.

3. Always adhere to standard safety regulations for electrical devices, power systems, and light-current installations, and ensure national safety regulations (e.g., VDE 0100) are observed.

4. If the device is to be connected to other devices (e.g., PC), the circuitry must be designed carefully. Internal connections in third-party devices may result in impermissible voltages.

5. If there is any risk involved in running the device, it must be switched off immediately and marked accordingly to prevent re-starting. Operator safety may be at risk if:

The device has visible damage.

The device is not working as specified.

The device has been stored under unsuitable conditions for an extended period.

In case of doubt, return the device to the manufacturer for repair or maintenance.

6. Warning: Do not use this product as a safety or emergency stop device, or in any other application where product failure could result in personal injury or material damage. Failure to comply with these instructions could result in death or serious injury and material damage.
