Tripping Safety-Chain Outputs; Prerequisites; Activation; Operation - Deif IMD 100 Series Integration Manual

IMD 100 Integration manual 4189360015 Rev. G
•
If the discharge is stopped due to missing 24 VDC, the remaining voltage across the ultra-
capacitors is approximately 100 V DC.
NOTE Mains voltage applied on the Mains input, ensures that the internal 24 V DC power supply
is functioning, even though the grid is off.
•
If the discharged is stopped by a command ("29:SE discharge OFF" or "0: Idle"), the remaining
voltage across the ultra-capacitors depends on the capacity and charge level of the ultra-
capacitors, discharge time, and the ballast resistor.
NOTE After deactivation the grid remains disconnected.

Tripping safety-chain outputs

It is possible to trip the safety-chain outputs (SCR1 and SCR 2) manually, which can be used for
example to trip the safety chain relay.

9.14.1 Prerequisites

There must be no active errors.

9.14.2 Activation

IMD Manager: Select "14:Trip SCR output" in the "States and special commands" in the "Monitor and
control" tab.
CAN/CANopen: send "14" to the special commands register (reg. 0x03)
The IMD will trip SCR 1 and SCR 2, and depending on the state it is in, change the state.
