12.5 Remote IPM Control
The IPM and RTM software have been changed to allow for the RTM digital input to be used to control
the IPM. This functionality is similar to that of the IPB/C/D.
The remote start can be set in two modes. In one mode it is always active and in the other mode it is
active only when the auxiliary digital input is closed. Remote start can also be disabled.
12.5.1 Function Overview
A previously unused parameter ca
lled „remote start‟, originally intended to implement the remote start
functionality, is
used to enable the remote start function. Setting it to „yes‟ enables remote start. Setting
it to „no‟ will disable remote start. Setting it to „Aux‟ enables remote start only when the auxiliary digital
input is closed.
The remote input (on the RTM) is edge sensitive. This ensures that if there is an upstream trip, the IPM
will not restart automatically once the power is restored. It also allows the keypad and external digital
input stops to work sensibly so that if the IPM is stopped locally, it will not restart immediately after any
of the stop are released.
When remote start is active, the remote input is closed to start the IPM and must remain closed while
the IPM is running. The remote input is opened to stop the IPM.
