4.4 Cycle time "t"

It is the time period (in seconds) that the controller uses to calculate its output.

e.g. When t = 2, if the controller decides output should be 10%, the heater will

be on 0.2 second and off 1.8 seconds for every 2 seconds. Smaller t values

result in more precision control. For relay or contactor output, it should be set

longer to prevent contacts from wearing out too soon. Normally it is set to 20 ~

40 seconds.

4.6 Decimal point setting "dP"

In case of thermocouple or RTD input, dP is used to define temperature display

resolution.

When dP = 0, temperature display resolution is 1º (C or F).

When dP = 1, temperature display resolution is 0.1º (C or F). The temperature

will be displayed at the resolution of 0.1º for input below 1000º and 1º for input

over 1000º (C or F).

4.7 Limiting the control range, "DIL" and "DIH"

1) For temperature sensor input, the "DIL" and "DIH" define the set value range.

DIL is the low limit, and DIH is the high limit. Sometimes, you may want to limit

the temperature setting range so that the operator cannot set a very high

temperature by accident. For example, if you set the DIL = 100 and DIH = 130,

operator will only be able to set the temperature between 100 and 130.

2) For linear input devices, "DIL" and "DIH" are used to define the display span.

For example, if the input is 0 - 5V. DIL is the value to be displayed at 0V and

DIH is the value at 5V.

4.8 Input offset "SC"

SC is used to set an input offset to compensate the error produced by the

sensor or input signal itself. For example, if the controller displays 5ºC when

probe is in ice/water mixture, setting Pb = -5, will make the controller display

0ºC.

4.9 Output definition OPA

This parameter should be kept at zero for this model.

4.10 Heating, and Cooling Mode Selection "COOL"

When COOL = ON, the controller is set for cooling control.

When COOL = OFF, the controller is set for heating control.

4.11 Temperature Unit Selection, Celsius or Fahrenheit, "C, F"

This parameter sets temperature units, C for Celsius, F for Fahrenheit. When it

is for current or voltage input, this parameter is voided.

4.12 Output range high limit "OUTH"

OUTH allows you set the output range high limit.

OUTH can be used when you have an overpowered heater to control a small

subject. For example, if you set the OUTH = 50, the 5000W heater will be used

as 2500W heater (50%) even when the PID wants to send 100% output.

4.13 Lock up the settings, parameter "LOCK"

To prevent the operator from changing the settings by accident, you can lock

the parameter settings after initial setup. Table 4 shows the privileges

associated with each lock code.

Note: to limit the control temperature range instead of completely locking it,

please refer to section 4.7.

4.14 Set Time for Timer "TE1" and "TE2"

"TE1" is for setting value for the timer. Press ▼ for 3 seconds and change the

value directly.

"TE2" is for setting time of timer 2, it is only valid for dual timer working mode.

4.15 Time Unit and Timer Counting Mode "UPT"

UPT = 0, timer counting down in seconds.

UPT = 1, timer counting down in minutes.

UPT = 2, timer counting up in seconds.

UPT = 3, timer counting up in minutes.

4.16 Timer control mode "INT" *

INT = 0. The timer is disabled. The controller functions as a regular dual

display controller. The lower display shows the set temperature instead of time.

INT = 1. The timer starts after the temperature reaches set point. When set time

reaches, controller's output stops and timer relay pulls in (turns on). It can be

connected to a buzzer to warn the operator.

INT = 2. The timer starts after the temperature reaches set point. When set time

reached, relay pulls in. The controller's output will continue to be on.

INT = 3. The timer starts after the temperature reaches set point. When set time

reaches, controller's output stops. Relay pulls in when timer starts and drops

out when it reaches the set time.

INT = 4. Timer function is independent of temperature controller. After powered

up (or reset), timer starts. The relay will pull in (close) when it reaches the set

time.

INT = 5. Timer function is independent of temperature controller. After powered

up (or reset), timer starts and the relay pulls in (close). It will drop out (open)

when it reaches the set time.

INT = 6. Timer function is independent of temperature controller. After powered

up (or reset), the relay drops out (open) for preset time TE1, then pulls in for

preset time TE2. This process cycles (dual timer cycling mode).

INT = 7. Timer function is independent of temperature controller. After powered

up (or reset), the relay drops out (open) for preset time TE1, then pulls in for

preset time TE2. The relay will remain drop out (open) until reset. After reset,

the relay will keep open for preset time TE1 then pulls in for preset time TE2

again (dual timer no cycling mode).

INT = 8. Timer function is independent of temperature controller. After powered

up (or reset), the relay pulls in for preset time TE1 then drops out (open) for

preset time TE2. This process cycles (dual timer cycling mode).

Note *:

i). When INT value is greater than 0, timer is enabled. The bottom of the display

is for time. In order to let the timer controls the Alarm 1 (AL1), ALP1 should be

set to 0.

ii). Terminal 11 and 12 must be jumped together to enable the timer. Timer can

be started either at powering up of the controller if terminal 11 and 12 are

shorted together, or at shorting terminal 11 and 12 if they are not shorted

together.
