4.5.3. Manual mode

Manual mode allows the user to control the output as a percentage of the total

heater power. It is like a dial on a stove. The output is independent of the

temperature sensor reading. One application example is controlling the

strength of boiling during beer brewing. You can use the manual mode to

control the boiling so that it will not boil over to make a mess. The manual

mode can be switched from PID mode but not from on/off mode. This controller

offers a "bumpless" switch from the PID to manual mode. If the controller

outputs 75% of power at PID mode, the controller will stay at 75% when it is

switched to the manual mode, until it is adjusted manually. See Figure 3 for

how to switch the display mode. The Manual control is initially disabled (A-M =

2). To activate manual control, please make sure At = 3 (section 4.4.3) and

A-M = 0 or 1 (section 4.16). If you are currently in ON/OFF mode (At = 0), you

will not be able to use manual mode.

4.6 Cycle time "t"

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

For example, when t = 20, if the controller decides output should be 10%, the

heater will be on 2 second and off 18 seconds for every 20 seconds. 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.

4.7 Input selection code for "Sn"

Please see Table 3 for the acceptable sensor type and its range.

and P-SH

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

display resolution.

dP = 0, temperature display resolution is 1 ºC (ºF).

dP = 1, temperature display resolution is 0.1 ºC . The 0.1 degree resolution is

only available for Celsius display. The temperature will be displayed at the

resolution of 0.1 ºC for input below 1000 ºC and 1 ºC for input over 1000 ºC.

2) For linear input devices (voltage, current or resistance input, Sn = 26-37).

4.9 Limiting the control range, "P-SH" and "P-SL"

1) For temperature sensor input, the "P-SH" and "P-SL" values define the set

value range. P-SL is the low limit, and P-SH is the high limit. For example,

sometimes you may want to limit the temperature setting range so that the

operator can't set a very high temperature by accident. If you set the P-SL =

100 and P-SH = 130, operator will only be able to set the temperature between

100 and 130.

2) For linear input devices, "P-SH" and "P-SL" are used to define the display

span. e.g. If the input is 0-5V. P-SL is the value to be displayed at 0V and P-SH

is the value at 5V.

4.10 Input offset "Pb"

Pb 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.

4.11 Output definition "OP-A"

This parameter is not used for this model. It should not be changed.

4.12 Output range limits "OUTL" and "OUTH"

OUTL and OUTH allow you set the output range low and high limit.

OUTL is a useful feature for a system that needs to have a minimum amount of

power as long as the controller is powered. e.g. If OUTL = 20, the controller

will maintain a minimum of 20% power output even when input sensor failed.

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

subject. e.g. If you set the OUTH = 50, the 5000 watt heater will be used as

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

4.13 Alarm output definition "AL-P"

Parameter "AL-P" may be configured in the range of 0 to 31. It is used to define

which alarms ("ALM1", "ALM2", "Hy-1" and "Hy-2") is output to AL1 or AL2. Its

function is determined by the following formula:

AL-P = AX1 + BX2 + CX4 + DX8 + EX16

If A = 0, then AL2 is activated when Process high alarm occurs.

If A = 1, then AL1 is activated when Process high alarm occurs.

If B = 0, then AL2 is activated when Process low alarm occurs.

If B = 1, then AL1 is activated when Process low alarm occurs.

If C = 0, then AL2 is activated when Deviation high alarm occurs.

If C = 1, then AL1 is activated when Deviation high alarm occurs.

If D = 0, then AL2 is activated when Deviation low alarm occurs.

If D = 1, then AL1 is activated when Deviation low alarm occurs.

If E = 0, then alarm types, such as "ALM1" and "ALM2" will be displayed

alternatively in the lower display window when the alarms are on. This makes it

easier to determine which alarms are on.

If E = 1, the alarm will not be displayed in the lower display window (except for

"orAL"). Generally, this setting is used when the alarm output is used for control

purposes.

For example, in order to activate AL1 when a Process high alarm occurs,

trigger AL2 by a Process low alarm, Deviation high alarm, or Deviation low
