Instruction Manual

It is prohibited for an individual, other than an approved user or a technician responsible for installation and repair from 

the head office, to install a gas leak detector on site or open the cover of the installed gas leak detector and manipulate 

it. This may cause serious loss of life and property from fire, explosion, and etc. In addition, please check whether there 

is any remaining explosive gas or combustible material in the surroundings. Power must be turned off before performing 

work.

■ Using OC1, OC2, and OC3 shown in the layout above, HART Option RS-485 MODBUS board can be attached. 

  3ØScrew holes located at top left of option board are used for fixing.

[Figure 3. Slotted Set Screw]

■ After detaching the cover, disassemble the display parts 

  as below.

  ①  Push in left and right fixing rings located on front 

   

side of LCD at the same time.

  ②  While pushing, pull the display parts towards the 

   

front to detach from gas detector body.

  ③  After detaching the display parts, the Main PCB 

   

is installed at the bottom part of the detector body.

■ <Warning - Do not open when electical current is 

 flowing>

■ Turn the slotted set screw (M4 x 1ea) fixing the 

  cover part of main body 3~4 tuns counter 

  clockwise (ccw) using a hex wrench (M2) then 

  turn the cover of gas leak detector ccw to detach 

  the cover. When the cover is detached, 

  LCD appears.
