XMTD-308 Intelligent Digital temperature controller

XMTD-308 Intelligent Digital Temperature Controller

Ⅰ.Summarize

XMT*-308 series Intelligent Temperature Controller, is single row 4-LED display. The controller can input kinds of signals which are used interchangeably, three-button operation, adopts ON/OFF control and PID control. It can select Fahrenheit and degree centigrade temperature display. It allows an easy parameter setting and convenient inputting, is used widely temperature automatic control systems of machinery.chemical.ceramics.light industrial.metallurgy.petrifaction and heat treatment and so on.

Ⅱ.Main Technical Indexs

First Menu	1		High-limit alarm	Determined by and	-	Random
	2		Measurement deviation	-20.0~20.0	Measuring value can be modified through increasing or decreasing this data.	0
	3		Proportion time	0~99.9~200	When the P↑, the proportion and differential function↑; If the P↓, the proportion and differential function↓ When P=0,the meter is ON/OFF control.	15.0
	4		Calculus time	0~3000	It`s used to adjust static difference. To increse it ,the static difference will bereduced, but when it is too high, the static difference will drift instability.	240
	5		Differential time	0~200	It`s used to adjust the overshoot in the First time, to increase it can reduce the overshoot.	30

Ⅵ.Operation

1. Electrify after take into the power, Sensor and control circuit according to the connection scheme, and then the instrument start testing itself for 1 second.

2. Set the setting value

Press ▲or ▼key 3 second enter to the setting value states. press▲or ▼key to modify,for long time to press the key can accelerate. After modification, press SET to save and exit. if you don`t do this operation, it can be done itself.

3. Interior Technical parameter setting(Technical parameter refer to the sheet)

(1) The first menu

Press SET key 3 second enter into the first menu, the window display parameter code then display parameter value. Press▲or ▼key to modofy,for long time to press the key can accelerate. .After modification, press SET key to save and enter into next Indexs setting. if you don`t do this operation, it can be done itself.

(2)The second menu

Press SET & ▲ key to enter into the second menu, and the setting method is the same as the first menu.

4. Set by itself

First ,set the setting value, and enter the menu, set to , and the AT light turn on,the meter enter the condition setting itself,this time the meter adopt on/off control mode, after three times surge(first time, measure value and display by turns; second time, measure value and display by turns; second time , measure value and display by turns),the meter confirm new.. and save it, the meter reset and(display. by turns) enter control condition.
