Operating life of electrical
components The underlying failure rates of electrical components apply within the usable operating life in accordance with
IEC 61508-2 Section 7.4.7.4 Note 3.
!
Note!
Correct installation is essential to the safe operation of the Deltapilot S.
Behavior of device when in
operation and in case of failure The behavior during operation and in case of failure is described in Operating Instructions BA332P.
Alarm response and current
output Increased security during parameter entry
When using this configuration method, the Deltapilot S outputs a permanently configured error current
≥
22 mA when the safety function is triggered or in the event of device errors.
!
Note!
If you selected the "On" option for the ACK. ALARM MODE parameter and an alarm occurs, proceed as
follows:
– Rectify the cause of the alarm.
– Unlock the Deltapilot S via the SAFETY LOCK and SAFETY PASSWORD parameters.
– Acknowledge the alarm via the ACK. ALARM parameter.
– Select the "Lock" option for the SAFETY LOCK parameter.
– Enter the password for the SAFETY PASSWORD parameter.
– Confirm the values and option selected for the parameters queried.
– Lock the Deltapilot S via the password.
Standard device configuration
Configure the current output for an alarm condition via the parameters OUTPUT FAIL MODE (default value:
max. alarm) and SET MAX. ALARM (default value: 22 mA). These parameters can be set to the following
values:
#
Warning!
When using the Deltapilot S as a subsystem of a safety function, the "Hold meas. value" setting may not be
selected as this option does not provide failsafe alarming.
