3. Installation
Note;
•
Do not mount the GOT in an environment that contains dust, soot corrosive or conducive
dust, corrosive or flammable gas, or expose the unit to high temperatures, dew
condensation, rain and wind or impact and vibration.
If the GOT is used in such a place, electrical shock, fire, malfunction, damages or
deterioration may be caused.
•
Never drop cutting chips or electric wire chips into the ventilation window of the GOT when
drilling screw holes or performing wiring. Such chips may cause fire, failure or malfunction.
•
Make sure that the power is turned off, before securely connecting any cables. Poor
connection may cause malfunction.
The GOT is designed to be mounted in a panel. Install it using the following procedure.
1) Preparing the panel surface.
On the panel surface, cut a rectangular mounting slot with the
dimensions shown on the right.
At this time, a space of 10 mm is required at each of the top and the
bottom sides of the slot, inside the panel for metal fixtures as shown in
"4) Dimensions required inside the panel for installation".
Note
Make sure that the thickness of the panel surface is no more than 5 mm (0.20").
2) Inserting the GOT into the panel surface
Attach the packing seal to the GOT, and insert the GOT from the
front face of the panel surface.

b) GOT
c) Mounting slot
3) Fixing the GOT
Put hooks of the mounting brackets (supplied) in to the mounting
holes in the GOT. Tighten mounting bolts (also supplied) until the
GOT is securely fixed.
Fix mounting bolts in all four positions, above and below the GOT.
a) Clamping bolt
b) Mounting bracket
Note:
Make sure to tighten the clamping bolts with a torque of 0.3 ~ 0.5 N# # # # m.
4) Peeling of protective sheet
Make sure to peel off the protective sheet on the surface of the product before use.

When installing the GOT,
make sure that the inside
dimensions shown on the
right are available.

b) Packing seal
4. Wiring for Power Supply
Caution:
Cut OFF all phases of power source externally, before installation or wiring work in order to
avoid electric shock or damage to the product.
Note:
•
When wiring the power supply, use electric wires of 0.75 mm
drop will not occur. For crimp-style terminals, use M3 size. Securely tighten crimp-style
terminals with a torque of 0.5 ~ 0.8 N#m so that errors will not occur.
•
Insure correct termination of DC power source, incorrect connection may result in unit
failure or the GOT being burnt.
•
Attach a fuse of 2 A to the 24V DC power supply.
•
Perform grounding (100Ω or less) with an electric wire of at least 1.25 mm
Never perform common grounding of the GOT and a strong power system.
Note
•
Feed power to the GOT by an external power supply.
The service power supply of the programmable controller cannot be used.
(Confirm service power supply capacity of main unit or extension unit is more than the total
value of the current consumption of GOT, extension blocks and special function blocks.)
Slot to be
•
Even if instantaneous power interruption of less than 5 ms occurs, the GOT continues its
cut on panel
operation. When power interruption for considerable period of time or voltage drop occurs,
the GOT stops its operation. However, when the power supply is recovered, the GOT
automatically restar ts its operation. (The screen displayed just after recovery is

5. Maintenance
Cautions:
•
Correctly connect the battery for memory backup. Never charge, disassemble, heat, burn or
short-circuit the battery. If the battery is handled in such a way, bursting or fire may be caused.
•
Always power OFF and remove the GOT from the panel before starting the replacement
of the backlight and battery. If this is not the case, the backlight may be dropped and
subsequently cause injury, or electrical shock may be sustained.
•
Never disassemble or modify the GOT. Disassembly or modification may cause failure,
malfunction or fire. For repair, please, contact a service representative.
Note:
Make sure to turn OFF the power, before connecting/disconnecting cables.
If you connect/disconnect cables while the power is turned on, failure or malfunction may be
caused.
When repairing liquid crystal screen, please, contact a service representative.
5.1 Replacement of Battery
When the battery voltage drops, a control device (system information) set by the screen design software
turns ON. The control device interlocks with an auxiliary relay in the PLC. It is recommended to provide a
lamp while utilizing the output of the PLC so that voltage drop can be monitored outside the GOT.
For details of control devices, refer to the GOT-F900 Series Operation Manual.
Note:
For approximately one month after the control device for battery voltage drop turns ON, the
battery backs up the alarm history, sampling and the current time. When the control device
(system information) turns ON, replace the battery (FX
The screen data is stored in the flash memory. Even if the battery is totally worn out, the screen
data remains stored
