Ⅲ、Name and functions of the sections(consult)


(1)PV display Indicates the process variable (PV) with a red LED.

(2)SV display Indicates the setting value (SV) with a green LED.

(3)AT indicator When auto tuning function is ON, a green LED lights.

(4)ALM1 indicator When ALM1 output is ON, a red LED lights.

(5)ALM2 indicator When ALM2 output is ON, a red LED lights.

(6)OUT indicator When OUT is ON, a green LED lights.

(7)Mode key (SET) Switches the setting mode and registers the setting value and selected value.(Setting value and selected value are registered by pressing the mode key.)

(8)Data shift key (<)

(9)Decrease key (∨)Decreases numeric value of the setting value

(10)rease key (∧)Increases numeric value of the setting value.

Note: XMTG-7000 only has three keys, has not Data shift key and ALM2 indicator.

Measurement update

-20.0 to 20.0

Measuring value can be modified throughincreasing or decreasing this data.Note: It may be cause inaccurate racy of measuring value when you use this function. Please use the function carefully according to your situation.



Proportional band

0 to 9999

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



Integration time

0 to 3000s

It’s mainly used to adjust the static difference. To increase it, the static difference will be reduced, but when it is too high, the static difference will drift instability.



Differential time

0 to 2000s

When the I↓,the calculus function↑; I↑the calculus function↓.When I=0, no calculus function, it is PD adjustment instrument



Control period

1 to 120s

When the d↓,the proportion and calculus function↑; if d↑,the proportion and calculus function↓,but the differential function↑.When d≤t, it has no differential function

0- All the parameter can rework1- Only SP value can rework>1 All the parameter can not rework


Ⅴ、Display Status(consult) 


Note:  1. LC is key lock. It can rework all parameter when LC is 0. It can only rework SP value when LC is 1.

2. The no all meter have up wards parameters, only answer for correspond to function meter have corresponding parameters.

l Connect the power, the sensor and the external control circuit to the instrument refer to the connection figure. After these, turn on the power and then the instrument will at first begin to auto-test according to the program A, Band C.

A: All LEDS and all indicating lamps will be lighted to test the lighting-system whether good or not. If unlighted LED or indicating lamp were found, please stop using and transmit it to for repairation. (This procedure lasts for 0.5s)

B: The window PV (upper window) display “CJ”, the window SV is not display.

C: The window PV display model.

After the three procedures, the instrument will step into the normal measure-control state. The upper window PV display the value that the instrument is measuring and the lower window SV display the value set.

l If want to modify the value in the window SV, press the SET key 3 second when the instrument is in its normal display state, then the window PV will display “SP” and the window SV will point wink. At this moment press the key ∧ to increase the value or the key ∨ to decrease (Press the key ∧ or ∨ for a longer time to accelerate the speed of value setting). Press < key shift (like cursor). Press the key SET to certain the modified value. If no any other operation after modification, the instrument will automatically return to the normal display state and accept the modified value at the same time.

l If want to modify the value other than “SP”, press the key (SET+∧) 3 second when the instrument is in its normal display state to set the internal parameter. Please set the value in terms of the actual application. But please pay more attention to the three items “P、I、d”, these must be set by experienced engineer.

l Auto-man: the first set value is OK, after at being “1”, the “AT” indicating to it will light. The instrument begins working as the ordinary one with two control points and three states. After 3 cycles, it will certain the best PID value to the set point and store it forever unless the user’s modification or opening the “AT” function.

l The signal “HH” or “LL” in the window PV means that the sensor is out of connection or the measured value is overflow.

Ⅶ、Fault Analysis and Clearance

XMT*-9000 adopts advanced production process, and has the strict test before leaving factory, it improve the reliability of the meter .The usual fault is caused by the wrong operation or parameter setting .If you find the fault couldn’t be cope with, please record it,and contact with the agent or us. Sheet 7-1 is the usual fault of XMT*-7000 in the daily application:

Sheet 7-1 Common fault handling

fault symptom Analysis of causes Disposal  measurement
Abnormal power 1、poor contact of power cord  2、power switch without lose Check the power
Signal display do not correlate with the facts.(display‘HH’or‘LL’) 1、Sensor model mismatch2、wrong signal connection 1、check sensor model and meter interior input parameter 2、check signal wire
Abnormal output control 1、wrong connecting output wire 1、check output connection
