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 of the
dimensions shown on the right.
At this time, space of 10 mm is required at each of the top and the
bottom 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").

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) Dimensions required inside the panel

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
2
or more so that voltage
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 Class D (100
Ω
or less) grounding with an electric wire of at least 1.25 mm
2
.
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.)
•
Even if instantaneous power interruption of less than 1 ms occurs, the GOT continues its
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
determined by the working environment originally set.)

5. Expansion Module (F9GT-40FMB)
F9GT-40FMB has a built-in flash memory and can transfer screen data when installed in the GOT.
(When installed in the OS earlier than version 1.40, screen display is not available while transferring data
from F9GT-40FMB to the GOT.)
For the use methods and specifications, refer to the manual for F9GT-40FMB.
6. 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 replacement of
the battery. If this is not the case, 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 backlight and liquid crystal screen, please, contact a service representative.
6.1 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 (system information) for battery voltage
drop turns ON, the battery backs up the alarm history, sampling and the current time. When
the control device turns ON, replace the battery (PM-20BL) soon.
The screen data is stored in the flash memory. Even if the battery is totally worn out, the screen
data remains stored
6.1.1 Replacement Procedure
1) Turn off the power to the GOT and remove the battery holder
cover.
2) Remove the existing battery from the battery holder, and
disconnect.
3) Within 30 seconds, connect a new battery.
4) Insert the new battery into the battery holder, and attach the
cover.
