Page 12: Device-Specific Safety Instructions
When a monitored IT system contains galvanically coupled DC circuits, an insu- lation fault can only be detected correctly if the rectifier valves (e.g. rectifier di- ode, thyristors, IGBTs, frequency inverters, …) carry a minimum current of > 10 mA. isoPV1685-1685PFR_D00007_02_M_XXEN/10.2016... -

Automatic self test All supply voltages are continuously monitored. The following tests are continuously carried out in the background: - Connection E-KE - System polarity - Residual current transformer (connection, short-circuit, isoPV1685PFR only) - Temperature measurement - Pulse generator isoPV1685-1685PFR_D00007_02_M_XXEN/10.2016... -
Page 19: Manual Self Test
When the self test is started via the CAN bus, you can choose between an insulation fault measure- ment test or a residual current measurement test (isoPV1685PFR only). isoPV1685(P): During the insulation fault measurement test, the alarm relay K1 (11-12-14) and K2 (21-22-24)are switched over. K3 is not switched over. -

Page 31: Bms And Can Bus
The RS-485 interface, galvanically isolated from the device electronics, serves as a physical transmis- sion medium for the BMS protocol. When an isoPV1685…or other bus devices are interconnected via the BMS bus in a network, the BMS bus must be terminated at both ends with a 120 Ω resistor. -
Page 32: Topology Rs-485 Network
The number of bus nodes is restricted to 32 devices. When more devices are to be connected, Bender recommends to use a DI1 repeater. 6.1.3 BMS protocol This protocol is an essential part of the Bender measuring device interface (BMS bus protocol). Data transmission generally makes use of ASCII characters. Interface data are: •... -

BMS and CAN bus The isoPV1685… can only be operated as BMS-SLAVE! BMS master A master can query all measured values, alarm and operating messages from a slave. If bus address 1 is assigned to a device, this device automatically represents the master. That means that all addresses between 1 and 150 are cyclically scanned via the BMS bus for alarm and operating messages. -
