9 Glossary
Bulkhead connectors Connections for attaching the differential pressure measurement hoses.
Configuration Parameter settings
Differential pressure monitor
Device function that monitors two configurable ∆p switch points.
Differential pressure ∆p Difference between the pressure on the clean gas side and the pressure
on the crude gas side of the filter.
Forced cleaning Forced cleaning cycle, independant of the current status of the control
sequence.
Service hours The filter maintenance interval in hours configured under Parameter 09
"Service hrs."
Service hours counter Internal hour counter that must be reset to 0 hrs after each filter service
(see Parameter 10)
Time function Relay contact 11, 12, 13 switches after the configured time elapses for
the configured period of time.
Timer See time function
Two-key menu control The menu for parameter configuration can be operated with the two keys
and
.
Two-position controller
Controller with two switch points (here: ∆p max and ∆p min)
∆p controller
Device function for implementing differential pressure dependent clean-
ing
∆p max alarm switch point
Differential pressure value, which when exceeded causes the message
"dP max alarm" to appear and relay contact 17, 18, 19 to switch.
∆p max switch point
(also abbreviated as ∆p
max)
Upper switch point of the two-position controller, which when reached
causes relay contact 11, 12, 13 to switch thus starting differential pres-
sure dependent cleaning.
∆p min alarm switch point In the case of device function ∆p controller:
Differential pressure value, which when decreasing (falling differential
pressure) causes the message "dP min alarm" to appear and relay con-
tact 14, 15, 16 to switch.
In the case of device function ∆p monitor:
Differential pressure value, which when exceeded (rising differential
pressure) causes the message "dP min alarm" to appear and relay con-
tact 14, 15, 16 to switch.
∆p min switch point
(also abbreviated as ∆p min)
Lower switch point of the two-position controller, which when reached
causes relay contact 11, 12, 13 to switch thus stopping differential pres-
sure dependent cleaning.
∆p remote display
Display that shows the differential pressure of the filter in a switch room.
