M102E/M501 TRS TROUBLESHOOTING & REPAIR
(Addendum to M101E Manual - P/N 04740 Rev A)
DO NOT manually alter the PID parameters of the M501-TRS temperature Controller
unless directed to do so by Teledyne Instruments customer service personnel.
In the event that the temperature controller of the M501-TRS must be replaced some initial
programming is required set the control functions if reprogramming is necessary. The following
tables define the approximate initial values for various processes control parameters. Once they
are set, perform an autotune procedure as defined in Section 6.4 of this addendum
10.6.1. Temperature Controller Primary Menu Parameters
NOTE
Tables 10-3 and 10-4 show the typical primary P-I-D parameter values for operation on
115V/60Hz with a set value of 1000°C.
The P, I and d values may be different for other AC main voltages (call Teledyne
Instruments customer service, and will vary somewhat after auto-tuning.
To set these parameters:
1. Open the appropriate menu
a. Press the SELECT key once to access the primary menu parameters. The main display will
show
.
b. Press and Hold the SELECT key for 3 seconds to access the primary menu parameters. The
main display will show
.
2. Use the SELECT , DOWN or 100’s UP key to scroll through the primary menu parameters until
the appropriate parameter is displayed (see Table 10-3 or Table 10-4).
3. Press the DATA key once. The current value of the parameter will be displayed.
4. To set each digit:
a. Press the up-arrow under that digit once. The digit will flash.
b. To increment that digit, press and hold the digit until the appropriate number is displayed.
c. To decrement that digit press and hold the DOWN key until the appropriate number is
displayed.
d. To increment/decrement the 1000’s digit it is necessary to adjust increment/decrement the
100’s digit up and down. Each time the 100’s digit passes “0” the 1000s digit will
increment or decrement correspondingly.
5. Once the desired value is reached, press the ENT key to store the new set Parameter value.
6. Press the PV/SV mode key to return to operational mode.
