How To Calibrate the 153/1253 Controller
The 153/1253 unit can perform five calibrations. They are:
•
Learn analog set point zero
•
Learn analog pressure zero
•
Learn analog set point full scale
•
Learn analog pressure full scale
•
Learn number of valve steps
You must issue these commands via RS-232 communication. To do this, connect a computer or
an MKS PT-1 to the 153/1253 controller.
Learn the Analog Set Point Zero
1. Supply zero input voltage on INPUT connector, J1, pin 9.
2. Send the Learn Analog Set Point Zero command:
Type Z1, and press ENTER
The 153/1253 controller learns the input voltage that corresponds to an analog set point
zero value. The analog set point zero value is set to 0.0 Volts at the factory.
Learn the Analog Set Point Full Scale
1. Supply full scale input voltage on INPUT connector, J1, pin 9.
Before you issue this command, be sure that the input voltage is at least 9% of the 10 V
full scale voltage. If the voltage is less than 9% of the typical full scale voltage, the
153/1253 controller ignores the learn command and retains the previous value. This
eliminates the possibility of learning an erroneous voltage value.
2.
Send the Learn Analog Set Point Full Scale command:
Type F1, and press ENTER
The 153/1253 controller learns the input voltage that corresponds to the analog set point
full scale value. The analog set point full scale value must be b1 and +10 Volts.
It is set to +10.0 Volts at the factory.
