Dryer Master DM510
Installation Manual
Electrical Installation Guidelines
General
1.
Analog signals from the field must be separated from other signal types and run in conduit
2.
Metal conduit is required for electrical noise shielding
3.
Communications cables must be run in conduit in plant environments. Surface wiring is
permissible in office environments
4.
Ensure all field components are identical to those shown on electrical drawings
5.
Ensure all field mounted level switches have been installed at specified elevations
6.
Ensure all field devices are labelled with their appropriate nameplates
7.
All manuals associated with instrumentation are to be available at site and are to be the
English version
8.
Ensure that all field wiring is tagged at each end
9.
All field wiring should be continuity tested. With the panel powered down, each field wire
should be individually connected to ground. The continuity to ground can then be measured
from the panel
10.
Once continuity testing has been done successfully, power can be applied to the panel
Wiring
Eight (8) 4-wire instrumentation cables need to be pulled from the dryer to the DM510 I/O panel to
the field instrumentation for the integrated I/O solution. Three (3) 16 AWG (minimum) ground wires
should be pulled from the DM510 chassis ground to specific field instrumentation and Dryer
’
s
Control panel.
For the remote I/O: two instrument cables (one as a spare) need to be pulled between the remote
I/O panel and the DM510 panel plus a 16 AWG (minimum) ground wire. It is recommended that the
grounding be a star configuration. (See Figure 21 - Star Point Grounding)
Instrumentation cable for each of the following:
1.
from the Inlet Moisture Sensor to DM510 panel
2.
from the Outlet Moisture Sensor to DM510 panel
3.
from the Sample Station (Calibration Push button) to DM510 panel
4.
from the Air Plenum Temperature sensor high temperature wire junction box to DM510
panel (if using an APT sensor). If the signal converter is used, from the signal converter to the
DM510 panel.
5.
from the Dryer speed control interface to DM510 panel (rate in/out)
6.
from the Dryer speed control interface to DM510 panel (local/remote)
7.
from the fan status contacts to the DM510 panel (if used)
8.
spare from Dryer Electrical panel to DM510 panel (optional)
9.
from the remote alarm to the DM510 panel (optional)
10.
for Remote I/O: communications and power wire from remote I/O to DM510 panel
11.
for Remote I/O: optional spare communications and power wire from remote to I/O to
DM510 panel
