Outputs
The DCR-1003 comes standard with 4 relay outputs fused at 5 A each. The
DCR-1004 is equipped with relays and an analog output. Detailed explanations
of the two output types are given in the RELAY and ANALOG sections.
RELAY
The four relays are fully programmable for ‘BEGIN’ and ‘END’ points and
‘TYPE’ of operation. The LEDs on the DCR indicate the status of the normally
open relays. When the LED is on, the relays are energized and the contact is
closed. For performing a distance to level measurement the zero point of
distance will be at the transducer. For volumetric or open channel monitoring,
the zero point will be at the empty point of the tank or flume. For distance
measurements the relay trip points will be programmed in the units selected in
mode 1. For volumetric or flow, the relays are in volume or flow.
MODE DESCRIPTION PARAMETERS EXPLANATION
12 Begin Trip 1 Units = mode 1 Sets the begin point
Default = 2.5 ft. of Trip 1
13 End Trip 1 Units = mode 1/mode 3 Sets the end point
Default = 2.9 ft. of Trip 1
14 Trip 1 Type Range = 0 - 7 Selects the type of
0 - near function Trip 1 will
1 - exclusive perform
2 - hysteresis near
3 - far
Set by NUM UP or NUM
4 - inclusive NUM DN
5 - hysteresis far
6 - disable
7 - fail-safe
Default = 0
15 Begin Trip 2 Units = mode 1/mode 3 Sets the begin point
Default = 3 ft. of Trip 2
16 End Trip 2 Units = mode 1/mode 3 Sets the end point of
Default = 3.4 ft. of Trip 2
