DESCRIPTION
The TC310VP is housed in a durable sheet metal and flame retardent plastic housing with display panel at
the front and wiring connections at the back. The seven segment LED display monitors measured value
continuously and the nine segment error bar shows the proximity to setpoint. Setpoint can be displayed by
depressing the setpoint changeover switch on the front panel. Setpoint adjustment is made by turning the
setpoint thumbwheel which is concealed behind the door on the front panel. Wiring connections are made at
the back by means of screw type connectors. All control adjustments are on the top of the instrument.
Dimensions
INSTALLATION
The instrument requires a 92X92mm panel cut out and is fixed by retainers positioned on the top and bottom
of the instrument. Maximum panel thickness is 10mm.
All external wiring is made to the rear of the instrument via M3 screw terminals.

CONTROL ADJUSTMENTS
Control adjustments.
SID - Switching Integral & Derivative; the use of switches to change integral and derivative time constant
simplifies the procedures in obtaining optimum control.
P1 - Proportional Band of 2.5-15% can be adjusted through this control.
P2 – Not used.
P3 - Manual Reset (optional) can be used to remove the steady state error inherent in PD control.
P10 – Not used.
P11 – Not used.
P12 - High/Low/Band Alarm (optional - only one type on any instrument) can be used to give a warning when
the measured temperature exceeds the alarm limit.
P13 & 14 – Valve open and close respectively. Valve Travel Time governs the speed of the valve motor in
response to small error (or PID) output demands; fully counter clockwise gives the slowest response and fully
clockwise, the fastest response.

TUNING
PID CONTROL TUNING PROCEDURE
1. Set P13 and P14 fully counter clockwise.
2. Set proportional band to minimum (P1 fully anticlockwise).
3. Set all SID switches to ’ON’ (11111111).
4. Adjust the setpoint to 10% below working temperature.
N.B. If it is undesirable for the system to overshoot the working temperature, perform the test at a further
reduced temperature.
5. Observe:-
a. Time (to) taken for the measured temperature to rise from the setpoint to a maximum.
b. Overshoot temperature (To) = maximum temperature - setpoint temperature.
6. Set the SID switches (see Table 1) to give ti = 4 x to. This will automatically set td = ti/9.
7. From the overshoot temperature, To, calculate the proportional band index PBI as follows:-
PBI = (To / TR) x 100
TR = 200 for -50 to 200 range
TR = 500 for -50 to 500 range
TR = 1000 for 0 to 999 range
and set the proportional band according to table 2.
8. Progressively reset P13 & P14 as far clockwise as possible without the introduction of system hunting.

PD CONTROL (OPTIONAL) TUNING PROCEDURE
1. Turn the manual reset to minimum (P3 fully anticlockwise).
2. Proceed as for PID control tuning procedure, use table 1 to set SID to give td = 0.5 x to.
3. Turn P3 anticlockwise to eliminate any steady state error.
ON-OFF CONTROL (OPTIONAL) TUNING PROCEDURE
No adjustment is required for ON-OFF control.

ALARM SETTING
PROCEDURE FOR SETTING ALARM ON TC310VP
For alarm setting purposes, the controller may be in either the control or the open loop mode, provided that
the input signal from the sensor to the controller remains steady at any convenient level during the short
period of time that it takes to set the alarm level.
1. STEPS IN SETTING UP A HIGH ALARM LEVEL
1.1 Ensure that the sensor input to the controller is at a steady temperature T1.
1.2 Turn the alarm setting control P12 fully clockwise.
1.3 Decide how many degrees above the set temperature the alarm must operate. Let this be t degrees.
1.4 By means of the thumbwheel, adjust the set temperature of the controller to be t degrees lower than the
sensor input temperature T1.
1.5 Adjust the alarm setting control P12 anti-clockwise until the alarm relay LED just comes on. The high
alarm will now operate at t degrees above any chosen set point temperature.
2. STEPS IN SETTING A LOW ALARM LEVEL
2.1 Ensure that the sensor input to the controller is at a steadytemperature T1.
2.2 Turn the alarm setting control P12 fully clockwise.
2.3 Decide how many degrees below the set temperature the alarm must operate. Let this be t degrees.
2.4 By means of the thumbwheel, adjust the set temperature of the controller to be t degrees higher than the
sensor input temperature T1.
2.5 Adjust the alarm settin congtrol P12 anti-clockwise until the alarm relay LED just comes on.The low alarm
will now operatre at t degrees below any chosen set point temperature.
3. STEPS IN SETTING UP A BAND ALARM
The band alarm operates when the actual temperature is t degrees higher than the set temperature or t
degrees lower than the set temperature. Therefore the band alarm may be set by setting up the high end in
the same manner as section one above or by setting the low end in the same manner as section two above.
