EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES.
The Modular Command Post System (MCPS), hereafter referred to as the tent, require a heat source.
This heater fulfills the need for an independent, powerful, self-powered, self-sustaining, self-regulating,
self-diagnostic heater.
The heater is set up for operation outside the tent. If operation inside the tent is desired, the optional
items in WP 0002 are required. The tent control assembly (with controls, visual advisory lights, and an
audible alarm) must be mounted inside the tent and a control cable (remote) used to connect the tent
control assembly to the heater.
The operation of the heater is controlled by the ON-OFF switch, the LOWER-HIGHER control knob (both
located on the control assembly), and the heater control assembly (located within the heater itself).
Manual movement of the ON/OFF switch to the ON position will cause the heater to automatically execute
a series of steps that lead to heater operation. Manual movement of the ON/OFF switch to the OFF
position will cause the heater to automatically execute a safe and orderly shutdown.
The status of the heater assembly can be determined by looking at the advisory lights on the tent control
assembly or by listening to the audible alarm. These lights and the related audible alarm are controlled by
the heater control assembly, which monitors the normal operation of heater, and, when an abnormal
operating condition is detected, cause the heater to shut off. Also, when an abnormal operating condition
is detected, the SYSTEM FAULT advisory light and the integral audible alarm are activated and pulse out
the following SYSTEM FAULT diagnostic codes:
