4. Operating procedure

Independent Overheat Prevention Device

This Equipment have redundant safety devices-1) Automatic Overheat Prevention (automatic reset)
function on the Controller, and -2) Independent Overheat Prevention Device(IOPD) with independent
power, circuit and sensor away from the Controller.

Main Relay of this Controller will be shut heater output power off when one of safety devices is
activated at Chamber internal temperature beyond its setting temperature.
Those functions will avail at Earth Leakage Breaker(ELB) ON

(｜).

Set temperature on Independent

Overheat Prevention Device(IOPD)

※

Set temperature with ▼▲ keys on its panel.

May stop its operation by activating

Independent Overheat Prevention Device(

IOPD) when the

difference between set temperature on IOPD and Target Temperature will be too close each

other.

Must set IOPD temperature at least 20

℃

higher than Target Temperature.

Note that the objective of this IOPD will not protect for samples but from overheating this

Equipment.

Factory settings and setting temperature ranges are as shown below:

Control Chamber stable at required temperature first, and let IOPD setting temperature down

by 1

℃

and then find out IOPD activating temperature, if IOPD will get to be activated at

required temperature.

Must wait for 5(five) seconds for the next 1

℃

down of IOPD setting temperature, because

its function will be operated to need some times.

Display

on Top Screen on Control Panel, if this IOPD is activated.

When you have set an operation temperature you want for IOPD , recording of the set

temperature takes several seconds and you need to wait for about five seconds before turning

the ELB off.
