5.2.1.3 Master unit controller configuration
The master unit‟s controller must be configured as a Master. Unless the unit was originally
shipped as an auxiliary (-AUX on model tag), it should be set to master already. If not, install
jumper W17 and remove jumper W18.
If the total system power is from 15 KW to 45 KW install jumper W13 on the Master Controller
board, 5005-721. In addition install W14 if the power is from 45 to 60 KW. Settings for W13 and
W14 on the auxiliary (-AUX) uni
t‟s controller(s) are not relevant.
KDC II Master or Auxiliary Controller jumper settings
Available configuration settings are shown in the table below.
Configuration Option W17 W18
Master 1 0
Auxiliary (-AUX) 0 1
Table 5-1: Master or Auxiliary Controller Configuration Jumper Settings
Relevant power level configuration settings for the MASTER controller only are shown in the table
below. The auxiliary units (-AUX) jumper settings for W13 and W14 are not relevant.
Check these settings if the system was not configured for parallel operation at this power level at
the factory.
Configuration Option W13 W14
Master, 5 KW, 10 KW 0 0
Master, 15 KW 1 0
Master / AUX 15 to 45 KW 1 0
Master / AUX 45 to 60 KW 1 1

Note: If the system was not configured for parallel operation at this power level at
the factory or has been reconfigured from its original shipped
configuration, it will be necessary to check the current programming
calibration.
This can be accomplished in one of two ways:
1. Check and as needed recalibrate the full-scale output current programming, or
2. Load the calibration coefficient for the selected mode of operation in the Calibration
screen.
Since the number of DC amplifiers is different when the master unit is used stand alone as
opposed to the Master of a multi-box system, the current loop gain will be different and thus the
current calibration will shift. To correct for this, the correct calibration coefficient must be entered.
If the same unit is used often as either a stand-alone master unit or a multi-box master unit, it is
advisable to note down the full-scale current calibration coefficients for each configuration.
See chapter 7.4 for calibration details.
