In the event of conflict between the text of this specification and the references cited herein (except for associated detail specifications, specification sheets or MS standards), the text of this specification shall take precedence. Nothing

11、in this specification, however, shall supersede applicable laws and regulations unless a specific exemption has been obtained. 3 REQUIREMENTS 3.1 General description. ILTEM consists of an electrical and hydraulic unit operating a three (3) inch diameter cylinder which forces a rotating drive shaft t

12、hrough an angular distance of 90 degrees. A removable electronic control unit provides front panel controls for on/off mode operations and hit sensitivity selection. Electronic selection and use of the hit sensor provide the ability to implement control functions such as the visual hit indicator lam

13、p, target response to hits, the gunfire simulator and the visual hit smoke scorer. 2 c Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-1-70698 (AR) 3.2 Fabrication. The ILTEM shall be manufactured in accor- dance with drawing 9375512 and MIL-F-13

14、926. The electronic control unit shall meet MIL-E-70694. 3 . 3 Functions . 3.3.1 Commands. The ILTEM shall receive through its elec- tronic control unit cohnarids to raise target, to lower target, to activate visual hit indicator lamp and gunfire simulator. 3.3.2 Mechanism control. The mechanism is

15、remotely controlled and responds as follows: a. Upon receiving a remote raise or lower command signal the mechanism moves the target to the position commanded. The mechanism does not respond in any manner if commanded to a position that it is already in. b. The mode of operation is selectable direct

16、ly on the target device by a rotary switch. At position 0 al1 electrical power is removed from the electronic control unit. At position I, the target can be raised and lowered by remote command and hits on the target have no effect. At: position 2, the target can be raised and lowered by remote comm

17、and and a hit on the target when raised will lower and stay lowered until another raise remote signal is received. At position 3, the target can be raised and lowered by remote command and a hit on the target will lower, delay 11 seconds, and then automatically raise until another hit causes it to r

18、epeat the above operation. At positions 4, 5 and 6 the visual hit indicator lamp will illuminate when the target is hit. Modes 4, 5 and 6 are the same as modes 1, 2 and 3 except for visual hit indicator lamp operation. c. The smoke scorer when connected, will operate when the target is hit, on modes

19、 1 through 6. The target device has a manual momentary switch that permits testing the raise and lower cycle and visual hit indicator lamp illuminations. 3.3.3 Hostile fire simulator control. The target device will operate a hostile fire simulator when a remote command (fire) is sent. accessible fro
