b. Parameter settings. These are the parameters that need to be changed from
the initial value: outy = 3 for PID mode with J1 relay output; ot = 20 to avoid
switching the contactor too often; for target temperature set SV = 1200° F.
10.2 A 24 V AC solenoid valve is controlled by J1 relay in on/off mode. The valve
should be on till the temperature reaches 200° F; once the temperature is above
200° F, it should be shut off. When the temperature drops below 195° F, it should
be turned on again. The power source is 120 V AC. The temperature sensor is a
type K thermocouple.

b. Parameter settings. These are the parameters that need to be changed from
the initial values: outy = 4 for using J1 relay in on/off mode; Hy = 5; SV = 200° F.
Note: if this is to control a contactor with 24 V coil, PID mode can be used. Then
the setting should be the same as example 10.1 except the SV value.
10.3 Drive a proportional control valve directly in cooling mode.
In a cooling system where the controller is connected to a linear control valve to
control the flow of the coolant. The target temperature is SV = 50° F. An PT100
RTD sensor is used to measure the temperature. A 120 V buzzer is connected to
the J1 relay which works as an absolute high temperature alarm, which should be
triggered at 54° F.
