It is possible to have a separate power supply between the TEDM (≤ 32 VDC) and the threshold contacts (≤ 60 VDC or ≤ 40 VAC). Configuration The three keys on the front panel are used to configure the following operating parameters: ● Switching point value for each threshold ● Switching hysteresis value for each threshold ● Active status for each threshold (NO or NC) ● Time delay of each threshold from 0 to 25 s in 0.1 s steps ● Auto-zero function ● Self test and parameter protection by a 4 digit code Additional parameter for the TEDM: ● Modbus slave address of the pressure switch ● Parity selection Maximum and minimum value consultation When the pressure switch is in the measurement mode it is possible to display or initialise the maximum and minimum pressure values saved at any time. Modbus communication The TEDM has a RS485 serial port and uses the Modbus RTU communication protocol. The Modbus protocol is a two-way exchange protocol based on a hierarchical data base structure between a master and multiple slave stations. It enables the user to read the pressure and the status of each threshold (open or closed). Exchange between the master and one slave: The master sends an order and waits for a reply. Exchange between the master and all slave stations: The master broadcasts a message to all the slaves in the network and they perform the order in the message without sending a reply. Two slave stations cannot talk together. The bus stations are identified by addresses given by the user. These addresses range from 1 to 247. Parameter consultation Parameters for each threshold, Modbus address (TEDM) and parity (TEDM) can be viewed whithout access code.
