Operation
8.1
Powering Up
The primary track being switched on, once a suitable magnetic field is detected, and if the pilot pins (pins 11 and 12 of the power
output connector) are shorted, the Regulator will be ready to be switched on. The output voltage will however appear at the power
output of the shrouded pin connector only if the Regulator is enabled at the interface plug. Enabling the Regulator can be done in
two different ways:
by making a connection between pin 1 (internal isolated 24 V) and pin 4 (enable),
by connecting an external 24 V supply. 0V to pin 2 and 24V to pin 4.
Note that when the Regulator is in the disable mode (pin 1 and 4 disconnected), the internal isolated 24 V supply is only suitable to
supply a starting signal to the Regulator itself; do not distribute externally! When the Regulator is enabled and the “status” relay is
closed (between pins 3 and 7), the maximum current allowed is 150 mA.
When the interface is not used:
Even if signals available through the interface plug are not being used, it is still
necessary to connect pin 1 to pin 4 for the
Regulator to start.
An optional “enable plug” is available for that matter, see chapter 14.3.
8.2
Powering Down
Turning off the primary track will immediately turn off all Regulators present on the track unless they are enabled. If a Regulator is
in an enable mode, the output voltage will decrease according to the load connected to it. This behavior allows continued function
(the length in time depends on the load needed at that point) even in the case where the IPT
®
power is temporarily interrupted (i.e.
the Track Supply was briefly turned off, a Pickup runs over an area where the magnetic field from the track is shielded… etc.)
Turning off a Regulator resets the error mode. It may therefore be required in the event of a fault to turn off a single Regulator,
instead of turning the track supply which would turn off all vehicles. Please, refer to chapter 10.4 to find out more on how to reset
Regulators.
If the need of turning on and off a Regulator exists even under load, using the interface plug is the best way to proceed; simply
break the contact with pin 4. It is not recommended to use the pilot pins to turn off a Regulator under load.
When a Regulator is turned off, the energy stored internally is discharged to reduce the output voltage to a minimum. For this
reason, the number of times a Regulator can be turned off (number of shutdown procedures) is limited to 3 within 30 seconds.
Exceeding this limit causes the Regulator not to respond and it will remain disabled (off) for the next 30 seconds.
