590+ Series DC Digital Converter
External AC Field (FL1, FL2)
(Not available on Frame 1 units)
If an external field supply is required to the controller for
application reasons, connect this supply to terminals FL1
and FL2. The magnitude of this voltage is determined by the
desired field voltage. The supply must be protected
externally with suitable fuses. Always derive the supply from
the Red and Yellow phases of the main power supply, with
the Red phase connected to terminal FL1 and the Yellow
phase to terminal FL2.
Note:
You must provide branch circuit and overload
protection. Use internal field connection for EMC
compliance.
IMPORTANT:
It is important that connection of the controller and the external field supply is consistent
when using an externally supplied field regulator. The supply must be derived from L1
(Red) and L2 (Yellow) phases directly or indirectly through a single-phase transformer. L1
must be connected to FL1, and L2 connected to FL2.
To change the controller from an internal to an external field type refer to Motor Field
Connections.
Thermistor (TH1, TH2)
Terminals TH1 and TH2 must be linked if sensors are not fitted.
The motor temperature alarm (THERMOSTAT) cannot be inhibited
in software.
We recommend that you protect the dc motor against overtemperature by the
use of temperature sensitive resistors or switches in the field and interpole
windings of the machine.
When the motor is fitted with over-temperature sensing devices, such as
thermostats or PTC thermistors, these should be connected (in series)
between terminals TH1 and TH2.
•
Thermistors must have a combined working resistance of 750
Ω
or less,
rising to 4k
Ω
at over-temperature. These thermistors are classified by
IEC34-II as Mark A.
•
Temperature switches must be normally closed, and open at rated
temperature.
The controller’s thermistor alarm will activate at
3k
Ω
.
The over temperature alarm is latched in software and must be reset by re-
starting the Converter.
