TM 55-1930-209-14&P-6 3-5.3 Emergency shutdown 3-5.3.1 General.  The barge has two emergency shutdown modes.  One mode shuts down individual systems such as the ventilation system or a diesel high pressure pump, and the other shuts down all barge operating systems. Both modes are activated by pushing a red button protected by a metal guard.  On individual system shutdowns, either fuel or electrical power is shut off to that system only.  On total shutdown, all fuel and electrical power is shut off to all operating systems. Seven  red  system  shutdown  buttons  are  located  on  the  ROWPU  space  starboard  bulkhead  just  aft  of  the personnel  door.    These  system  shutdown  buttons  (Figure  3-10)  control  shore  power,  ventilation  systems,  ROWPU  1 diesel high pressure pump, ROWPU 2 diesel high pressure pump, ship auxiliary generator, ship service generator 1, and ship service generator 2. Six red total shutdown buttons are located as follows: •   On ROWPU space starboard bulkhead aft of personnel door, above and forward of system shutdown buttons. •   Outside ROWPU space starboard door on weatherdeck. •   Outside ROWPU space port door on weatherdeck. •   Inside ROWPU space port door to weatherdeck. •   Outside dayroom door to weatherdeck. •   Inside dayroom door to weatherdeck. 3-5.3.2 Emergency shutdown procedures a. In an emergency, push the appropriate red button to shut down either a selected system or all operating systems. b. When  emergency  situation  has  been  corrected,  reset  emergency  button  by  turning  collar  behind  button  one- quarter turn clockwise.  Button will pop out and again be in the ready position. c. After emergency button is reset, any systems turned off by that emergency button must be restarted with their individual controls. Section IV.  Operation under extreme conditions 3-6  Operation  under  extreme  conditions.    Operation  of  shore  discharge  system  in  extreme  cold  creates  a  special problem  with  lubricants.    Other  problems  occur  during  operation  in  extreme  heat.    These  extreme  conditions  are discussed below.  Additional information is contained in the manufacturers' service manuals/instructions listed in Chapter 6.  See TM 55-1930-209-14&P-21 for operation of shore winch under unusual conditions. 3-6.1 Operation in extreme cold a. Heaters.  When oil temperature is 45 degrees F or less, set heater ON/OFF switch (Figure 3-3) to ON.  Make sure heater indicator light comes on. b. If hydraulic power unit motor does not start because temperature on weatherdeck is below 32 degrees F, it may be necessary to jog starter button (Figure 3-3) so that warmer oil in hydraulic power unit warms oil in lines on weatherdeck.    If  hydraulic  power  unit  motor  does  not  start  after  jogging  starter  button,  it  may  be  necessary  to heat hydraulic lines on weatherdeck. 3-6.2 Operation in extreme heat.  Motors.  Electric motors may have a tendency to run hot and stop due to overload.  It is best to allow the motor to start automatically after it cools off. 3-21
