- the ESPE/AOPD for t > TInt is released or
- before TInt has elapsed, if there are no more muting signals.
When parallel muting is activated, a parallel muting signal
(MP1 or MP2) may be released for the time
TInt.
The released signal must be re-operated within the time
specified under
TInt, or the other signal must also be released.
Parallel muting is switched off when:
- the ESPE/AOPD for t >
TInt is released (when MP1 = MP2 =
0) or
- MP1 and MP2 are released when the ESPE/AOPD has
already been released (when the muting signal is arranged in
a cross/star formation)
In general, muting is switched off when there are no more
muting signals.
• TMut : Timer Muting
This setting determines the maximum permitted muting time.
Permitted value range: 0 ... 511 (^
= 8.5 minutes)
Format: Word
Time unit: s
• TOPD: Timer (active) Optoelectronic Protective Device
This setting determines the maximum time permitted between:
“Muting ON” and “ESPE/AOPD interrupted” and:
“Muting sensor exited” and “ESPE/AOPD released”.
The time elapsing between the start of muting and the
interruption of the ESPE/AOPD must not exceed t = TOPD.
The time elapsing between exiting the last muting switch and
the enabling of the ESPE/AOPD must not exceed t = 2 x
TOPD.
Permitted value range: 0 ... 8191
Format:
Word
Time unit: ms
• TOff : Halt all muting timers
TOff = 0:
Muting timer active
TOff = 1: Halt all muting timers
For example, this input parameter could be connected to the
signal “Conveyor stopped”.
• AuSt: Start-up disabler on PSS start-up
AuSt = 0:
Start-up disabler (reset required on PSS start-up)
AuSt = 1: Automatic reset
