Page 4: Introduction
VISY-Output 8 is an 8-channel relay output module, installed in a case with the protection IP66. It connects the high-precision VISY-X tank gauging system to external safety devices or alarm indicators. With VISY-Output 8, different alarm conditions detected by the tank gauging system can be transferred to external devices. -
Page 5: Installation
Installation Safety Instructions When installing VISY-Output 8 following safety instructions must be observed: ● VISY-Output 8 is intended for operation within the VISY-X system only. ● Modifications to the VISY-Output 8 are prohibited without the prior consent of the manufacturer. -
Page 6: Prerequisites
Prerequisites To connect the VISY-Output 8 to the VISY-Command, the measurement evaluation must be available in the version VISY-Command VI-4 with connected communication adapter VISY- ICI 485 or in the version VISY-Command Web VPI, see Technical Documentation: VISY-Command VI-4, art. no. 207184 ... -
Page 7: Device Information
2.4.1 Device information Sticker of the VISY-Output 8 device number, which uniquely identifies the device. When using the device with the VISY-X tank gauging system, this device number is required for the configuration. 2.4.2 Connections 24-pin screw terminal for connection to the relay contacts... -
Page 8: Connection Of The Power Supply
Connection of the power supply The power supply (230 VAC) must be supplied using fixed wiring. The wires for the power supply are connected to the screw terminals marked with PE, N and L. Figure 2: Power supply screw terminal Connection of the relay contacts The VISY-Output 8 has eight output relays, each with a potential-free changeover contact. -
Page 9: Connection To The Measurement Evaluation Unit
Connection to the measurement evaluation unit … Up to eight VISY-Output 8 can be operated simultaneously with the VISY-X tank gauging system. To connect VISY-Output 8 to the tank gauging system it is recommended to use a 3-core cable with signal ground (GND connection terminal) to increase the noise immunity. -
Page 10: Configuration
3.1.1 … when connected to VISY-Command VI-4 The FAFNIR Output Box Protocol (OBP) is used for communication with VISY-Command VI- 4. Addressing is done via the individual device number of the VISY-Output 8. All switches must be set to the OFF position. -
Page 11: Access To Configuration
VISY-Output 8 is configured using the VISY-Setup configuration software. Wired version of the VISY-X system: If VISY-Output 8 is connected to the wired VISY-X system, the data protocol for communication with VISY-Stick must be set to “Multi Probe" using VISY-Setup. -
Page 12: Settings
Settings Changing the configuration adjusts the VISY-Output 8 to the requirements of the relevant application. The following settings are possible: ● Hold time after communication loss ● Output Action After Hold Time ● Relay mode ● Relay Delay After configuration, it should be checked whether the alarm signalling works as expected. -
Page 13: Relay Modes
Relay modes The following relay operating modes are possible: ● Standard mode In the Standard work mode, a relay is generally de-energised (passive), and will be energised (active) when the corresponding output is activated. ● Fail safe mode In fail-safe mode, a relay is generally energised (actively) and is de-energised (passively) when the relevant output is activated. -
Page 14: Fault Diagnosis
Fault diagnosis VISY-Output 8 has several LEDs to make diagnosis easier when there are problems. The position of the LEDs can be seen in Figure 1. Transmit LED TxD (7) / Receive LED RxD (8) The two red communication LEDs indicate, whether data are received or transmitted from VISY-Output 8. -
