Page 2-15 “HOLD/NON-HOLD Setting”
You can select whether to hold the operating status of operated internal switches or alarm output
relays. This setting applies to both the internal switches and the alarm output relays.
However, non-hold always applies to relays for which the reflash alarm is set, regardless of the hold/non-hold
setting.

• When 30 VAC or 60 VDC and more is applied to the output terminal of the alarm output module or the output
terminal of the DI/DO module, use double-insulated wires (withstand voltage performance: more than 2300
VAC) for those wires which apply 30 VAC or 60 VDC and more. All other wires can be basic-insulated
(withstand voltage performance: more than 1390 VAC). Furthermore, use “crimp-on” lugs (for 4-mm screws)
with insulation sleeves for connecting to the screw terminal. Make sure that the crimp-on tool must be one
specified by the crimp-on lugs manufacture, and that the crimp-on lugs and tool must be matched to the wire
size. To prevent from electric shock, do not touch the terminal after wiring and make sure to re-apply the
cover.
• To prevent fire, use signal wires having a temperature rating of 75°C or more.

• The overvoltage category of each input module is CAT ll (CSA1010-1).
• The measurement category of each input module is CAT ll (IEC61010-1).
• When connecting to a clamp terminal, use a signal conductor with the following cross-sectional width:

• To prevent electric shock, do not touch the terminals after wiring.
• Furnish a switch (double-pole type) to separate the instrument from the main power supply in the power
supply line. In addition, make sure to indicate that the switch is a power control for the instrument on the
switch and the ON/OFF positions of the switch.
Switch Specifications
Steady-state current rating: 3 A or more, inrush current rating: 90 A or more (AC power supply)
Steady-state current rating: 8 A or more, inrush current rating: 90 A or more (DC power supply)
Use a switch complied with IEC60947-1, -3.
• Do not add a switch or fuse to the ground line.
Page 4-13 “Clock Display”
The date and time can be displayed on sub-display 2.
According to the set time in 3.7 “Setting the Date and Time” (see to page 3-25), the current date
and time can be displayed.

• SINGLE:
• Digital print: The interval is determined by the chart speed and the number of columns to be printed. See
the table in chapter 14 (page 14-8).

If an error code appears on the display, see Section 13.4, “Error Codes.”
If servicing is necessary, or if the instrument is not operating correctrly though the following corrective actions
have been taken, please contact your nearest YOKOGAWA representative, dealer, or sales office.
