INTRODUCTION:
The Load Manager Mark IV is a 10-channel sequencer and load shedding
controller controlling 10 external relays that are supplied by the installer.
Provision has been made to permit the installer to sequence only a total of 5, 6,
7, 8, 9 or 10 channels. Those channels for which sequencing is not selected will
be energized constantly and controlled only by there own external, manually
controlled switches or by the load management circuits.
Load management for the 10 channels is completely independent of the
sequencing function. Ten “dip switches” are provided, one for each channel to
establish the load shedding priority. These switches permit an absolutely
arbitrary selection of the shedding sequence and in addition permit any of the
channels to be “locked out” and not be load shed under any circumstances.
INSTALLATION:
Install the Load Manager Mark IV in any convenient location where it is protected
from water or excessive temperatures. Figure 1 is an Installation and Wiring
Schematic illustrating the wiring of the manual control switches and relays.
NOTE
The LOAD MANAGER MARK IV is designed to operate relays. It is
not necessary to connect to all of the outputs. Any outputs at the
discretion of the installer may remain unused. Nothing need be
connected to the unused outputs. Relays must have a coil resistance
of 40 ohms or greater.
