INITIALIZE Screen
On the INITIALIZE screen, the equipment No. and communication conditions for
using the external communication function and the alarm range of secondary cooling
water temperature are set. The MEMORY SWITCH screen is displayed from the
INITIALIZE screen in order to switch a special function and set the alarm range of
secondary cooling water temperature.
How to see the displayed items
: Settable item
INITIALIZE Initializes the set values. After replacing the lithium battery, rewriting the program,
or replacing the CPU board, the set values may change or be lost. Accordingly,
perform initialization and set the values again.
When this button is pressed, it takes about 15 seconds until initialization is
completed. The POWER lamp blinks during that time. Turn off the power supply
after blinking stops. When the power supply is turned off during initialization (lamp
blinking), Error No.52 MEMORY TROUBLE occurs at the time of the next power-
on. At that time, press the button again.
NETWORK
Sets the equipment No. in the range of #00 to #15 to perform remote operations by
using the external communication function.
REF TEMP
ALARM
HIGH
LOW
Sets the control temperature of secondary cooling water. When the temperature
of secondary cooling water exceeds the set value, the solenoid valve for primary
cooling water is opened.
Sets the alarm temperature range by lower limit value (LOW) and upper limit value
(HIGH). Usually, it is not necessary to change the set value. When you must
change it for a compelling reason, contact us for information.
<Note>
When the temperature of secondary cooling water goes down below the value
set in "LOW", Error No.11 LOW TEMPERATURE OF COOLANT occurs. When
the above temperature exceeds the value set in "HIGH", Error No.10 HIGH
TEMPERATURE OF COOLANT occurs. If the temperature of secondary cooling
water does not reach "LOW + 2ºC or more" and "HIGH or less", Error No.10 or
Error No.11 occurs.
POSITION
AUTO-OFF Sets the time required for the guide light to go out automatically in the range of 01
to 98 minutes. This can be set in units of minute.
When 00 is set, no guide light is output.
When 99 is set, the guide light does not go out automatically.
Not used.
