4.3 Setpoint Configuration
The ‘switch on’ & ‘switch off’ limits define the points where the
output will go on and, possibly, back off. The relation between the
‘switch on’ limit and the ‘switch off’ limit defines the
direction of the
mechanism:
’Switch on’ limit > ‘Switch off’ limit: trigger on upwards change
When current reading is larger than 'switch on' limit, output goes
on.
٠ If the channel is defined as ‘Latch’, the output
remains on until
turned off manually.
٠ If the channel is defined as ‘Auto’, the output goes back off when
reading is smaller then ‘switch off’ limit.
’Switch on’ limit < ‘Switch off’ limit: trigger on downwards change
When current reading
is smaller than 'switch on' limit, output goes
on.
٠ If the channel is defined as ‘Latch’, the output remains on until
turned off manually.
٠ If the channel is defined as ‘Auto’, the output goes back off when
reading is larger then ‘switch off’ limit.
“Switch On” Limit
‘$A’ or ‘$B’ through ‘$H’
Sets ‘switch on’ limit for the specified channel (1-8).
PC must send channel’s letter and a string representing a
floating point value in the range -2000.0 to +2000.0 followed
by CR.
E.g., to set ‘switch on’ limit for channel 3 to 145.2 the PC
would send “$C145.2” with CR. Note, the ‘C’ is the channel
selection.
If the string is accepted as valid the TCIC returns “OK” with
CR/LF and stores the value in its non-volatile memory.
Else the TCIC returns “ERR” with CR/LF and does not store
the value.
