INSTALLATION GUIDELINES

  1. Prepare the cut-out with proper dimension as shown in figure.
  2. Remove clamp from Controller.
  3. Push the Timer through panel cut-out and secure the Controller in its place by tightening the side clamp.

SAFETY INSTRUCTION

MECHANICAL

  • Ambient temperature and relative humidity surrounding the Controller must not exceed the maximum specified limits.
  • The Controller in its installed state must be protected against excessive electrostatic or electromagnetic interferences.

ELECTRICAL

  • The Controller must be wired as per wiring diagram & it must comply with local electrical regulation.
  • The Electrical noise generated by switching inductive loads might create momentary Fluctuation in display, latch up, data loss or permanent damage to the instrument. To reduce this use snubber circuit across the load.

Mode
OIM Px - 413 PID Digital Temperature Controller - Display 26This function will be executed only if selected control action is PID.
Auto-tuning function is enabled by setting this parameter to ‘YES’. The decimal of LSB flashes till Auto tuning function is in progress. During Auto-tuning, Controller learns the process characteristics by itself & calculates required P, I & D values. User can cancel or abort this feature by setting this parameter to ‘NO’.
No

USER GUIDE:

ON-OFF ACTION: In this mode, Output (Relay/SSR) remains ON till actual temperature reaches to the set point value. On reaching SP, Output turns OFF & remains OFF till actual temperature drops down (in Heat logic) or raises (in Cool logic) equal to  hysterisis set by User. (As shown in Fig : 3.1 & 3.2)

OIM Px - 413 PID Digital Temperature Controller - Display 27

AUTO TUNING MODE: In this mode, Controller learns the process characteristics by itself and calculates the required P,I & D values. It can be performed at any time after power ON but, it is best to start it when the process is at Ambient temperature in order to minimize overshoot & undershoot. Auto tuning is applied in case of :

  1. Initial set up for a new process.
  2. Substantial change in SP from previous auto tuning value.
  3. Control accuracy is not satisfactory.
    If the control performance by using auto-tuning is still unsatisfactory, User can apply the further adjustments of P,I & D values as shown below
