Special Functions
A3.7.3 Inhibiting or Enabling the
Level Control for PZG Line
(Automatic Indication of
Changes in PZG Line Status)
Command syntax:
Code: PL
Parameter: .................... a
Possible entries / replies
0 = inhibit (OFF)
1 = enable (ON)
2 = extended function
By means of the command PL0 the level control
is inhibit.
By means of the command PL1 the level control
is enabled.
If the receive level exceeds the set digital level
threshold (see chapter A3.7.4), an open>
collector transistor will become conductive.
Thus output X66.9 (see chapter A2.6) is
connected to ground.
By means of the command PL2 the extended
function is enabled.
In addition to command PL1, after approx.
100!ms the string "U1" is emitted via the
RS232!/ RS485 interface.
Example 1:
Inquiry whether level control is inhibited or en>
abled
Command = rAxxPL??
Æ Reply = rAxxPL0?
The level control for PZG line is inhibited.
Example 2:
Enabling the level line control for PZG line
Command = rAxxPL1?
A3.7.4 Setting the Level Threshold
Command syntax:
Code: DS
Parameter: ................... a
Possible entries / replies
Range: ........................ 0 to 120
Stepwidth: .................. 1 dBoV
EMF
Entry: .......................... in dBoV
EMF
Note:
The level threshold is required for level control
of the PZG line (A3.7.3).
Example 1:
Entering a digital level threshold of
35 dBoV
EMF
Command = rAxxDS35?
Example 2:
Inquiry of the currently effective digital level
threshold
Command = rAxxDS??
Æ Reply = rAxxDS35?
A threshold of 35 dBoV
EMF
is set.
