4 Parameters
4.1 Altering Parameters
Each Zone (for description see chapter 3.6.1) can be configured with up to 29 so called Zone-parameters in
order to assign functionality as required by the end user.
The parameters are numbered with a capital P followed by 2 digits and have particular names in case they are
not spare parameters for future use.
Parameters P01 through P15 could be altered by the end user operating through the TCD 01 tracing control
display (see chapter 3.10). However the Parameters P01 through P15 can be password protected in order to
avoid unauthorised access (see chapter 3.3.2).
Parameters P16 through P29 are pre configured by the heat tracing supplier, they should not be altered dur-
ing operation at all. Only in case a heat tracing circuit has been physically changed, changes should be made
by responsible (heat tracing design) engineer.
Changing Parameters P16 through P29 is possible by:
1. Set DIP 2 of 5 pole DIP switch of AF TC1/4/5 to ON-position (see TC 816 Hardware Configuration
Guide).
2. Use one of the following tools to alter Parameters P16 through P29:
- TCD 01 (single phase current display) with firmware AZ871 rev.2.41 or higher
- TCD 01 (three phase current display) with firmware AZ884 rev.2.32 or higher
- Paracon software running on a PC through converter USB or RS232 to RS285
- Visual Fecon monitoring software running on a PC through converter USB or RS232 to RS285
4.2 Zone Parameters to be configured through TCD 01 tracing control display
4.2.1 Parameter P01:
LO-ALARM
This Parameter is:
•
Valid for Temperature Controller Zones
- Zones 1 through 16
- unit in: °C or °F
•
Not valid for Limiter Zones
•
Valid for Current Zones
- Zones 17 through 32
- unit in: 0,1 x A => value of 10 means 1 A
Measurement below the value set for parameter P01 triggers the respective zone
LO-ALARM , this results
in:
•
tripping the appropriate Lo -alarm contact on the AF TPA Thermon Power supply module AC
•
the Lo -LED on the AF TPA module lights up red
Adjustment thresholds: 0...630
Default value:
0
NOTE:
LO-ALARM
is not supervised when the reference set point in the circuit display is set to “0” or
operation mode (P06:
OP MODE
) is set to OFF.
