Sorensen DCS Series Manual Addendum

1.1 INTRODUCTION

This addendum covers the M133, M135 and M136 option operation, a
M9 or M130 remote programming option for the DCS series power
supply with an Isolation Relay and Reverse Polarity Relays PCB.
The Isolation Relay PCB is an assembly which is attached to the DCS
externally; when installed it adds 3” to the length (see Figure 1). This

option allows the user to fully isolate the DCS output from it’s load as

well as provide local or remote sense control.

1.2 FEATURES AND FUNCTIONS

All features remain as described in the DCS-E 1KW Series manual and
Section 1 of the M9C GPIB (P/N M361667-01) or M130 Ethernet
programming manual (P/N M362797-03). See section 2.2 of this

document for sense connection differences from base model.

1.2.1 Additional Features and Functions

 Output voltage isolation from output load.
 Output local or remote sense operation.
 Relay hot-switch lock-out; ensures that the voltage across

the relay contacts and the current through them is zero prior
to changing relay states.

 Relay automatic disconnect; relays automatically latch open

when a shutdown occurs.

1.3 PROGRAMMABLE FUNCTIONS

All programmable functions remain as described in Section 1 of the M9
or M130 manual.

1.3.1 Additional Programmable Functions

 Remote Isolation Relay control
 Remote Local/Remote Sense Relay control
 Remote Reverse Polarity Control

1.3.2 Readback Functions

All readback functions remain as described in Section 1 of the M9 or
M130 manual.

2.1 CONFIGURATION

The M9 (GPIB) or M130 (LXI Ethernet) and the Relay PCB options are
installed at the factory. Use the setup procedure described in the M9 or
M130 programming manual section 2 to configure the M9 or M130 and
Relay PCB for your system and application.

2.2 EXTERNAL SIGNAL CONTROL USER CONNECTOR

The control signals accessible at connector J5 are the M9 signals
extended thru the relay PCB from the M9 external user control signals
are as described in paragraph 2.3 of the M9 programming manual.

The control signals accessible at connector J3 are the DCS 1KW J3
signals extended thru the relay PCB from the DCS 1KW rear panel are
as described in paragraph 2.4.2 – 2.4.3 of the DCS 1KW Operation

Manual. NOTE: Do not use the sense connections at J312

and J3-13 – Sense connection must be made at the J9
Pins 1 and 2.

A 6-pin Molex J9 provides access to the isolated remote sense signals
J9-1 and J9-2. The mating receptacle for the 6-pin connector is Molex
43025-0600. Remote sense J9-1 connects to the +side of the load and
J9-2 to the –side. Also accessible is the non-isolated DCS output voltage
on J9-5 (+) and J9-6 (-).

3.1 IEEE 488.2 or Ethernet and SCPI COMMAND
OPERATION

The M9 and Relay PCB operation by remote programming using the M9
IEEE-488.2 and SCPI command sets are as described in section 3 of the
M9 programming manual.
