Overview Of The Operating And Display Elements; Commissioning Of The Dryer - Parker Zander WVM Series Operating Manual

Overview of the operating and display elements

The operating panel at the switch cabinet door allows for the monitoring of the
operating statuses and for the modification of settings. The display is a Touch
Screen Panel. To operate, touch the elements on the screen.
For further information on the operating panel and the controller's functions,
please refer to the enclosed controller manual.
Vessel pressure gauge
On both vessels, pressure gauges are fitted which show the operating
overpressure. The operating overpressure indicates the operating phase of the
relevant vessel:

During adsorption the pressure gauge should indicate the nominal operating
overpressure.

During regeneration the indication of the pressure gauge on the regenerating
vessel
—
—

During the pressure build-up phase the indication on the pressure gauge
should again rise to operating overpressure level (both vessel gauges
indicate the same operating pressure).

Commissioning of the dryer

Risk of injury from escaping hot regeneration gas!
Hot humid air might escape from the the regeneration gas outlet at the
vacuum pump. Therefore, keep clear of the blow-off outlet during
operation of the unit.
Risk of injury from crushing!
During the switching from adsorption to regeneration, there is a risk of
injury from crushing at the universal shaft and the drives. During
switching, stay clear of these components!
Risk of injury from hot surfaces!
During operation, certain surfaces of the dryer are heated to temperatures
of over 120 °C. At insulated dryers, screw connections might protrude
from the insulation. Do not touch hot surfaces. Allow surfaces to cool
before you carry out any work at the dryer.
Risk of injury from suddenly escaping gas!
While the unit is under pressure, never remove any components or
otherwise interfere with the dryer! Suddenly escaping gases can lead to
serious injury!
Prior to any work, release all pressure from the unit.

must drop from the operating gauge pressure to < 0.5 bar gauge
pressure during the expansion phase,
must indicate a vacuum of 50 – 100 mbar during the drying phase.
