To use the on/off mode, set At = 0. Then, set the Hy to the desired range
based on control precision requirements. Smaller Hy values result in tighter
temperature control, but also cause the on/off action to occur more frequently.

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 that power level
when transitioned into 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"
Cycle time 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. If the load is a heater, t should be set to
2 seconds. If the load is contactor, it should be set to 20~40 seconds. The
default is set to 10 second for motor type load.

4.8 Decimal point setting "dP"
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 0.1ºC . The 0.1 degree resolution is
only available for Celsius display. The temperature will be displayed at the
resolution of 0.1ºC for input below 1000ºC and 1ºC for input over 1000ºC.
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. 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 feature for the systems that need to have a minimum amount of
power as long as the controller is powered. For example, 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. For example, if you set the OUTH = 50, the 5000 watt heater will be
Pins
used as 2500W heater (50%) even when the PID wants to send 100% output.

4.13 Alarm output definition "AL-P"
4, 5
Parameter "AL-P" may be configured in the range of 0 to 31. It is used to define
4, 5
which alarms ("ALM1", "ALM2", "Hy-1" and "Hy-2") is output to AL1 or AL2. Its
4, 5
function is determined by the following formula:
4, 5
AL-P = AX1 + BX2 + CX4 + DX8 + EX16
4, 5
3, 4, 5
If A=0, then AL2 is activated when Process high alarm occurs.
3, 4, 5
If A = 1, then AL1 is activated when Process high alarm occurs.
3, 4, 5
If B = 0, then AL2 is activated when Process low alarm occurs.
3, 4, 5
If B = 1, then AL1 is activated when Process low alarm occurs.
4, 5
If C = 0, then AL2 is activated when Deviation high alarm occurs.
4, 5
If C = 1, then AL1 is activated when Deviation high alarm occurs.
4, 5
If D = 0, then AL2 is activated when Deviation low alarm occurs.
4, 5
If D = 1, then AL1 is activated when Deviation low alarm occurs.
4, 5
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
2, 5
easier to determine which alarms are on.
2, 5
If E = 1, the alarm will not be displayed in the lower display window (except for
4, 5
"orAL"). Generally, this setting is used when the alarm output is used for control
4, 5
purposes.
