in all receivers; therefore descriptions have been combined for the purposes of this document.
CommandPro

series receivers contain sophisticated programs coupled to electrically tough interfaces.

These power systems offer several advantages:



Safety – Three levels of safety ensure safe operation even in the event of circuit failures.



Reliability – Wide use of surface mount parts and few interconnections between boards provide
greater reliability and easier service.



Simplicity – Easy diagnostics and simple troubleshooting procedures makes servicing quick and easy.



Versatility – programmability plus many options allow this system to work on virtually any equipment
without modifications to the basic control system.

The receivers consist of one or two circuit boards mounted inside either a NEMA 4 steel enclosure or a

NEMA 12 extruded aluminium enclosure.
