7. REMOTE AND ANALOG PROGRAMMING
7.1. Introduction
The rear panel connector J1 allows the user to program the power supply Output voltage and
Output current limit with an analog device. J1 also provides monitoring signals for Output
voltage and Output current. The programming range and monitoring signals range can be
selected between 0-5V or 0-10V using the setup switch SW1. When the power supply is in
Remote Analog programming, the Digital communication (RS-232/RS-485, LAN, IEEE or
USB) is active and can be used to read the power supply operating parameters.
CAUTION
COM (J1-12), VPGM_RTN (J1-22) AND IPGM_RTN (J1-23) terminals of J1
connect internally to the negative Local Sense potential (-LS) for models with
Vout < 30V. COM (J1-12) and VPGM_RTN (J1-22) terminals of J1 connect
internally to the negative Local Sense potential (-LS) for models with 30V
≤
Vout
≤
600V. Do not connect these terminals to any potential other than negative
Local Sense (-LS), as it may damage the power supply.
CAUTION
When the Isolated Analog Option is installed, do not apply any signals to the non-
isolated VPGM and IPGM (J1-9 and J1-10) pins. All other J1 features may be
used normally. Refer to Section 4.5 for a description of the J1 connector features.
7.2. Local/Remote Analog Selection
J1-8 (Fig.4-4) accepts a TTL signal or an Open-Short contact (referenced to J1-12) to select
between Local or Remote Analog programming of the Output voltage and Output current
limit.
In Local mode, the Output voltage and Output current limit can be programmed via the Front
Panel VOLTAGE and CURRENT encoders or via Digital communication (RS-232/RS-485,
LAN, IEEE or USB). In Remote Analog mode, the Output voltage and Output current limit
can be programmed by analog voltage or by programming resistors via J1-9 and -10 (Refer
to Sections 7.4 and 7.5). Refer to Table 7-1 for the Local/Remote Analog control (J1-8)
function and Setup switch SW1-1, -2 settings.
