1. General Informat on
In most applications the bentrup TC500 series controller (TC505 and TC507) can adapted by the
controller configuration as described in the operating instructions Appendix C (simple
configuration mode). However, some applications require controller features which can not be
accessed by the simple configuration mode (Examples: Using motorized valvues, adapting error
conditions etc.).
2. Extended Conf gurat on Mode
In the Extended Configuration Mode you can access the entire controller structure and adapt
your bentrup TC500 series controller to virtually all applications. You change parameters of
every control loop, combine outputs logically, assign inputs to any outputs etc. More than 2000
parameters leave you enough options for even most strange applications.
To change the controller to Extended Configuration Mode an internal jumper needs to be set.
pen the controller and located the jumper bridge. Set the jumper as shown
After changing to the Extended Configuration Mode all parameters are set corresponding to the
simple configuration mode. In other words, setting the jumper does not change any operation
mode by itself. However, when you enter the configuration mode the parameter display looks
different as described in the following chapter.

3. Chang ng Parameters n the Extended Conf gurat on Mode
Enter the configuration mode as usually (pess and hold key „select“ until display changes). The
controllers display appears as shown:
TC505 TC507
1 table number 5 keys to select row
2 column number 6 keys to select column / table
3 row number 7 keys to directly select table
4 parameter value 8 keys to change value
The configuration parameters of the TC500 controllers are organized as 12 tables. Every table
specifies one kind of parameter (e.g. table 0=real time clock, table 1=misc. adjustments, ..).
Each row of the table holds one parameter; multiple columns specify settings for repeated
devices (e.g. one column for each control output).
Please find as an example the digital output configuration table (control outputs):

DI........................digital input (e.g. status input)
A ......................analog output (e.g. 0-10V output)
AI........................analog input (e.g. measure input)
The number following this designator specifies the input/output. Examples:
D 0.0................1st switching output of the controller
D 0.1................2nd switching output of the controller
AI 0.0..................1st analog input (e.g. thermocouple) of the controller

Use the keys as specified before to navigate through the parameters and modify as requested.
Since also minor changes of the parameters might cause major changes in controller operation
you need to familiarize yourself entirely with the configuration.
To save the changes permanently press and hold the key „select“ and keep it pressed until the
display shows „Sav. kY“. If you release the key too early (e.g. during „Sav.CfG“) all changes
will be lost! Note: If you get mixed up with the parameter changes at anytime simply turn off
and turn back on the controller to return to the previous parameter settings.
4. Deta led Explanat on of all Parameters
All paramters are explained in detail. See file „TC500.html“ (german) or TC500e.html (english)
supplied as a seperate file.
5. Chang ng Parameters by a PC
If your TC500 controller is fitted with a RS232 or RS485 interface you can use the free bentrup
software WinConfig to do all parameter changes very easy. WinConfig makes parameter setting
simple as well you can save configurations on disk and reload etc.
The RS232 or RS485 interface can be also added to exisiting TC500 controllers at very
reasonable costs. The configuration table shown earlier in this manual is a screenshot from
WinConfig.
6. Return ng to S mple Conf gurat on
Simply remove the jumper to return to Simple Configuration Mode. This configuration mode has
priority ie. the TC500 controller will disregard all enhanced configuration mode settings.
7. Chang ng type of Thermocouple S/R to J/K and v ce versa
Usually type of thermocouple should not be changed from S/R to J/K since different
compensating cable is needed. However, if this is considered this change is done by adjusting
the other jumper (marked as „T/C J/K“, see chapter 2.). Note: This only applies if the controller
operates in simple configuration mode. Keep in mind that mismatch of thermocouple and
controller setting causes severe damage to the kiln and goods. 5

bentrup TC505/507 Configuration Table Version 1.12
Table 0: clock / calender
The controller uses its real time clock / calender for different purposes. It allows the automatic commencing of
programmes at predefined times as well the real time clock / calender is used to time stamp logged data and
events. When configuring the controller using bentrup WinConfig / WinControl the controller is automatically
updated with the PCs time / date information, Therefore manually changeing time / date is disabled

Table 2: analog input
Specifies the analog input signals for the controller. Analog inputs are used to connect sensors like
thermocouples, resistors, voltage/current signals to the controller. You can exactly define signal type (voltage,
resistance, current) as well as signal range, signal conversion and correction, unit etc. The most common signal
types are predefined. Each column of the table defines one process value which are named IN00, IN01 etc. The
maximum number of analog input depends on the hardware.
.
00: input mode
(options END, T/C, LIN, ATMS, RES)
type of the analog input signal. Choose the appropriate kind of signal conversion from the given options:
T/C: Thermocouple input type. Selection of thermocouple and compensation mode see parameter below
LIN: Linear input type for generic use. This mode is used to convert any kind of linear input signal (as defined in
the corresponding parameters) into its process parameter. An example for a typical application is to convert a
4-20mA signal from a pressure transducer into 0 to 100 Pa process parameter
ATMS: Atmosphere signal conversion. Use this selection to convert the typical signal of a circonoxyde probe
into the kiln atmosphere reading. The controller uses the equation of Nerntzsch to convert the probe signal
into % of oxygen. The probe temperature required for oxygen calculation is specified in the corresponding
parameters as well as the kind of gas required for the carbonmonoxyde calculation. Note below on
temperatures below 650°C no oxygen calculation is done (no reliable probe signal)
RES: Resistance temperature sensor conversion. Converts the resistance characteristic of most commonly used
resistance sensors (like Pt100) into temperature reading
01: signal source
(value range AI0.0 to AI1.0)
Specifies a physical input (AI..) of the controller. The process parameter is created from the signal on this
physical input. To create two different process parameters from one physical input make sure that both signal
types and ranges equals
02: average cycles
(value range 1 to 11)
Specifies the low pass signal filter. This options is used to smoothen the input signal. Can be used to eliminate
signal interference as well as to improove signal quality. Setting this option to "1" disables the filter. A higher
setting causes higher smoothening (low pass frequency is 1/n Hz). A setting of 4 suits most applications.
03: units
(options °C, °F, °K, dg, mV, mA, O2, CO, %, ev, mb, m³, m³h, kh, kwh, Pa, AT)
Specifies the unit of the process value
04: trim +/- %
(value range -10.0 to 10.0)
Allows full scale input signal correction. In certain applications it is required to compensate for any deviations
of the installation. Example: Setting this parameter to -5.0% will cause the process value to be trimmed to 95°C
instead of 100°C. Note: This parameter should be used with care since on most applications deviations errors
should to be compensated by eliminating the real cause of the deviation rather then compensating on the
controller
05: offset +/- val
(value range -10.0 to 10.0)
Allows zero offset signal correction. Adjust this parameter if you need to adjust the input offset value. Note:
This parameter should be used with care since on most applications deviations errors should to be
compensated by eliminating the real cause of the deviation rather then compensating on the controller
06: min value
(value range -9999 to 9999)
Minimum value of the process value. Specifies the lower value limit of the process parameter. Any lower value
is respected as underrun (causing an error)
07: max value
(value range -9999 to 9999)
Maximum value of the process value. Specifies the upper value limit of the process parameter. Any higher

9
value is respected as overrun (causing an error)

Adapt the jumper settings of the physical input accordingly (done automatically on some devices)
19: val.@zeropoint
(value range -2000.0 to 2000.0)
Process value at lower reference of input value. Example: A pressure transducer supplying 4 to 20mA at -250 to
+250 Pa. Set this parameter to "-250" since this is the process value at the lower reference of 4mA
20: val.@fullscale
(value range -2000.0 to 2000.0)
Process value at upper reference of input value. Example: A pressure transducer supplying 4 to 20mA at -250 to
+250 Pa. Set this parameter to "250" since this is the process value at the upper reference of 20mA
following parameters apply on selection ATMS only:
28: temp. source
(value range IN00 to IN03)
Selects the process value representing the temperature of the atmosphere sensor. The temperature is required
for the calculation of the oxygen
29: min. CO temp
(value range 600 to 1800)
Minimum temperature in centigrade Kelvin required for carbonmonoxyde calculation. A minimum
temperature of 900°C (1273°K) is recommended for reliable calculation

Table 6: programme table
The programme table determines the parameters and the sequence to be entered for each programme
segment. The first programme parameter is always a time followed by a temperature. Depending on the
application the following programme segment parameters could be for instance offset temperatures (for
multizone kilns), programme events etc. The parameter sequence after the 1st temperature is variable;
however, keeping all programme EVENTs togather saves programme memory
.
00: value type
(options END, TIME, VAL-L, ---, VAL-S, EVENT, ATMS)
Select the kind of value in each column of the programme table:
TIME: The very first column of the programme table holds the segment time

temperature etc.)
---: selection not used
VAL-S: Programme value in the range of -127 to 128. Typically used for any kind of relative values (like offset
temperature for zones)

Table 7: process flow
The parameters of this section specify the reaction of the controller to any kind of unusual conditions that
might happen during a programme run. Examples for unusual conditions are broken temperature sensors, heat
up problems of the kiln, control channel errors etc. As well the conditions to enter the next segment during a
running programme can be adjusted as required
.
00: time in ramps
(options KEEP, UPDAT)
If the temperature of the pilot input (IN00) is higher than the start temperature of the ramp the time of the
ramp can be either kept or reduced accordingly
KEEP: Segment time is kept, setpoint begins as programmed
UPDAT: Segment time is reduced accordinly. Example: Segment 0 is 0°C, segment 1 is "in 2 hours to 500°C".
Assuming a kiln temperature of 250°C when starting the firing, the time is reduced to 1 hour (causing a setpoint
of 250°C)
01: monitor ch
(value range -CH02 to CH02 )
Only the channels specified are monitored for process problems. This setting allows to include only the
channel(s) which are important for the process. Either a single channel can be selected (e.g. on single zone
kilns) or a range of channels (e.g. ch00 to ch02 on a 3 zone kiln). A range is entered as minus channel (e.g. "-
ch02" stands for ch00 to ch02)
02: temp match %o
(value range 0.0 to 100.0)
An uncontrolled ramp (SKIP) the end of the segment is determined by match of actual temperature and final
segment temperature. Since the controller slows down temperature move at the end to avoid
over/undershoot it might take some time to finally reach the temperature althought it is not required by the
process. This parameter allows to specify a window to earlier complete the segment. Example: 2.0 ppm of
1320°C (max. channel temperature) = 2.64°C, SKIP segment ends at 997.36°C assuming a final ramp

17
temperature of 1000°C
03: num of matches
(value range 1 to 250)
An uncontrolled ramp (SKIP) is only completed if the temperature matched the specified number of cycles. The
check is done each 0.5 seconds. This is used to avoid leaving the segment if the temperature only overshoots
for a short time. Example: The setting of 6 lets the controller to complete the current segment if the
temperature matched for at least 3 seconds
04: end of SKP seg
(options DISR, WAIT.X, INFIN)
An uncontrolled ramp (SKIP) usually is only completed if the actual temperature reached the final ramp
temperature. The following options are considered:
DISR: Causes the controller to disregard the temperature, ie. to leave a SKIP segment immediately
WAIT.X: Causes the controller to wait for temperature match, but maximum for the specified time (see next
parameter). This option is strongly recommended on multi zone kilns, e.g. at a time of 10 minutes. Otherwise
the process might lock up itself. For instance in a cooling SKIP, the thermocouple of zone 2 has a little deviation
an therefore zone 2 is heated 4°C higher; if the heating affects zone 1 this zone will never cool down as
neccessary. The time begins to count if the first zone starts to control. If the time is elapsed the segment is
finished disregarding the temperature of the zones matches
INFIN: Causes the controller to wait for temperature match for infinite time
05: max wait (sec)
(value range 0 to 9999)
wait time in seconds for the feature specified previously
06: act.on CH unco
(options DISR, WAIT.BR, WAIT.CO, INFI, INFI, INFI)
In a controlled ramp it might happen that the kiln temperature can not follow the requested increase although
the controller asks for maximum heating (resp. the requested decrease in a cooling segment). The following
actions can be selected:
DISR: Causes the controller to disregard this situation
WAIT.BR: Causes the controller to hold the firing to give the kiln temperature time to catch up. If the kiln
couldn't catch up within the specified time (see next parameter) the firing is interrupted (break). The hold
mode (same as hold used during programme run) can also be released manually by pressing the hold skip
button
WAIT.CO: Bei dieser Einstellung hält der Regler den Brennvorgang ebenfalls an, führt den Brennvorgang aber
nach der eingestellten Zeit fort, wenn die Temperatur nicht aufholt wird
INFI: Causes an immediate break if the temperature can not follow.
07: max hold (sec)
(value range 0 to 9999)
wait time in seconds for the feature specified previously
08: uncontr = ..CH
(options ALL, ANY)
Selects the criteria the controller judges to the kiln as non following the temperature increase:
ALL: all channels out of control (maximum or minimum heating)
ANY: any channel out of control

Table 8: programme setpoint
The programme setpoints are calculated according to the programme resp. temperature curve entered by the
operator. Some adjustments are possible for easy operation. Automatic setpoint calculation required for
cascade control systems is also entered by the following settings
.
00: setpoint type
(options END, CON, MOD, CHA)
The following basic types creating a setpoint can be selected:
CON: Use initial value of the programme segment only. Typical applications are offset values for zone
temperatures or flap positions
MOD: Programme setpoint modulated by the segment time. This is the common setting causing the
programme setpoint to count upwards resp. downwards over the segment time (e.g. within 2:00 hours from
0°C up to 1000°C)
CHA: Setpoint calculated by cascade control algorithm - for details refer to the example below
following parameters apply on selection CON only:
01: table source
(value range CH/Z2 to TA04)
Selects the column of the programme table used for setpoint calculation. TA01 is the 1st column, ie. usually the
primary temperature
02: offset src SP
(value range OFF, SP00 to SP02)
Defines a setpoint which refers to an existing setpoint, ie. the setpoint is calculated by adding another setpoint
to it. Used e.g. for the setpoint of the slave zones of a multizone kiln. Using this option allows the operator to
enter the temperature of the slave zones as offset (temperature difference) relative to the master zone
setpoint. In this example the master zone setpoint is entered in this option
03: idle setpoint
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature
04: error setpoint
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature
following parameters apply on selection MOD only:
11: table source
(value range CH/Z2 to TA04)
Selects the column of the programme table used for setpoint calculation. TA01 is the 1st column, ie. usually the
primary temperature
12: offset src SP
(value range OFF, SP00 to SP02)
Defines a setpoint which refers to an existing setpoint, ie. the setpoint is calculated by adding another setpoint
to it. Used e.g. for the setpoint of the slave zones of a multizone kiln. Using this option allows the operator to
enter the temperature of the slave zones as offset (temperature difference) relative to the master zone
setpoint. In this example the master zone setpoint is entered in this option
13: idle setpoint
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature
14: error setpoint
(value range -9999 to 9999)
Setpoint whenever the controller is not in a programme run (IDLE). Can be used to ensure a certain
temperature is maintained without a programme run. Entering "0" switches off this feature

19
following parameters apply on selection CHA only:
21: based on SP
(value range SP00 to SP02)
Selects the programme setpoint used for the cascade control, ie. the programme setpoing for the target
22: charg.ctrl.CH
(value range CH00 to CH02)
Selects the master control channel (loop). The basic idea of a cascade control is as follows: An application
requires a large target (e.g. a piece of aluminium) to follow a temperature curve. An appropriate solution is
using an air convection kiln. Using an ordinary control it will give different problems depending on the position
of the thermocouple: When sensing the ambient temperature the actual temperature of the target
(aluminium) will be far (might be even hundreds of degrees centigrade) behind since it is very lag. Sensing the
target temperature might cause damage to the kiln since the controller does not pick up the temperature of
the heaters. Additionally, temperature oscillations are likely when the target temperature is getting close. A
cascade control eliminates these problems and works as follows: Two control channels are combined. The
master control channel is configured as normal, ie. using the programme temperature as setpoint and the
target temperature as actual temperature. The output of this channel is used to create a 2nd temperature
setpoint according to the settings in this section. This setpoint and the actual ambient temperature are
assigned to the slave control channel driving directly the heating device of the kiln. Note that the master
control channel is configured as heating/cooling loop with a wide proportional range and slow integral time
(P/I/D = 10.0% / 400 s / 0 s)
23: max. temp.diff
(value range -9999 to 9999)
Limits the maximum difference in temperature between the target and the ambient temperature. Used to
avoid damage of the target if sensitive. A high limit, however, speeds up the process of the target reaching the
programme setpoint
24: max envir.temp
(value range -9999 to 9999)
Limits the maximum ambient temperature. Used to avoid damage of the target if sensitive. A high limit,
however, speeds up the process of the target reaching the programme setpoint
.
.
Table 9: control channel
The control loops are designed to operate in totally different modes. Each operation mode can be tuned
individually
.
00: ctrl.algorithm
(options END, PID, C-PID, D-HYS, P-DIR, ---)
Depending on your application different control algorithms are available
PID: Default control algorithm suitable for most applications
C-PID: As before, but provides independent disable feature for heating and cooling range. Important on
heating/cooling applications where heating and cooling depends on external conditions. Also used to avoid
heating and cooling ranges chasing each other. Activation is done by any bit (e.g. a digital output). Typical
applications are gas kilns where heating range (0 to +100%) is disabled once the burner control bit goes OFF
D-HYS: Hysteresis control for heating devices which require either temperature deviation or do not allow short
cyclic activation (e.g. discontinuous burners)
P-DIR: Direct control. The setpoint is directly converted into a control value refering to the given value
boundaries. Typical application is setting a flap position directly (e.g. 0 to 100%)
01: setpoint chn
(value range SP00 to CH19)
Selects the setpoint used for this control channel
02: input chn
(value range SP00 to CH19)
Selects the process value used for this control channel

20
03: power % on ERR
(value range -100 to 100)
Predefined process output if an error occurs in the control channel. The control channel enters error state if a.)
the process value fails (overrun, underrun, invalid), b.) the process value exceeds the process value limit
specified in the channel configuration or c.) the gradient check indicates failure
04: maximum value
(value range 0 to 9999)
Maximum process value. Used to limit the process input value for safety reasons as well as setting the
operation range. If the process value exceeds the limit the control channel enters error state which can only be
cleared by re-starting the programme. Set this value above the actual operation range to allow overshooting
05: grdnt check s
(value range 0 to 3600)
The gradient check is used for safety reasons. Prevents the unit from damage if the feedback signal (e.g. the
thermocouple) fails. Checking the increase of the process value is performed on maximum output (typically
+100%). This parameter defines the checking period in seconds. Set to "0" to disable checking. If the gradient
check determines an error the channel is switched off (gradient error state)
06: grdnt chk dif
(value range 0 to 9999)
Increase of the process value required per checking period on maximum heating
07: ctrl charact
(value range 0 to 3)
Depending on the application select the operation range of the control channel to one of the following options:
0 = 0% to 100% / 1 = 100% to 0% / 2 = -100% to +100% / 3 = +100% to -100%
following parameters apply on selection PID only:
08: prop. band %
(value range 0.0 to 999.9)
Control parameter "proportional band" in % of the maximum value
09: integral time
(value range 0 to 9999)
Control parameter "integral time" in seconds
10: derivat. time
(value range 0 to 9999)
Control parameter "derivative time" in seconds
11: prop. shift
(value range 0 to 4)
Determines the operating range of the proportional band: 0 = prop. band below setpoint / 1 = prop. band one
quarter above setpoint / 2 = .. half above setpoint / 3 = .. three quarters above setpoint. In most applications a
setting of "1" ensures best results (ie. fast reaching the setpoint with minimum overshoot)
following parameters apply on selection C-PID only:
18: prop. band %
(value range 0.0 to 999.9)
Control parameter "proportional band" in % of the maximum value
19: integral time
(value range 0 to 9999)
Control parameter "integral time" in seconds
20: derivat. time
(value range 0 to 9999)
Control parameter "derivative time" in seconds
21: prop. shift
(value range 0 to 4)
Determines the operating range of the proportional band: 0 = prop. band below setpoint / 1 = prop. band one
quarter above setpoint / 2 = .. half above setpoint / 3 = .. three quarters above setpoint. In most applications a
setting of "1" ensures best results (ie. fast reaching the setpoint with minimum overshoot)
22: + activat. DOx
(value range OFF, DO0.0 to DO1.0)
Selects the bit (digital output) which activates the positive operation range (heating). When the bit is off the
