2. Safety 2.1 Intended use The universal measuring device PEM575 is suitable for the analysis of energy and power monitoring of the power supply quality data recording for energy management. As a compact device for front panel mounting, it is a replacement for analogue in- dicating instruments.
Safety 2.3 General safety instructions Bender devices are designed and built in accordance with the state of the art and accepted rules in respect of technical safety. However, the use of such devices may introduce risks to the life and limb of the user or third parties and/or result in dama- ge to Bender equipment or other property.
3. Device description 3.1 Area of application For humans, electric current is not immediately visible. Universal measuring de- vices for monitoring electrical parameters are used wherever energy consumption, performance measurements or the quality of the supply voltage are to be made vi- sible.

Device description The accuracy of the active energy metering corresponds to class 0.2 S in compli- ance with the DIN EN 62053-22 (VDE 0418 Part 3-22):2003-11. The large display of the panel mounting device makes the relevant measured quantities easily legible and enables fast configuration. In addition, the RS-485 in- terface allows a central evaluation and processing of data.

Logging 8.3 Data recorder (DR) PEM575 has an internal memory of 4 MB and provides 4 high speed data recorders 12 standard recorders Each of these recorders can record 16 parameters. The data recorders are program- med solely via the communications interface.
Logging Notes: table 8.2 The data recorder is only operational when the parameters 1…4 are all non-zero! "Recording delay": In Trigger mode 1, a fixed time can be set in seconds to delay the start of the measurement (triggered by timer). Example: "300" means that the recording will take place at 5 minutes after the DR is enabled.

Modbus Register Map Notes: table 10.33 The data recorder only becomes active if the offset entries +1, +2, +3 and +6 marked in the table are non-zero! High-speed data recorders can be triggered by a timer (the internal clock) or a setpoint. In trigger mode 2 when the setpoint goes active, the recorder starts to record, and when the setpoint becomes inactive, the data recorder stops.

Modbus Register Map 10.18 Time setting There are two time register formats supported by PEM575: 1. Year/Month/Day/Hour/Minute/Second register 9000…9002 2. UNIX-time register 9004 When sending the time via Modbus communications, care should be taken to only write one of the two time register sets. All registers within a time register set must be written in a single transaction.
Page 160
Modbus Register Map PEM575 supports the execution of commands to the outputs in two steps (ARM before EXECUTING): Before sending an open or close command to one of the out- puts, it must be activated first. This is achieved by writing 0xFF00 to the appropriate DO register.
