16. OTEMP (Over Temperature) indicator: Red LED lights when an over temperature
shutdown has occurred.
17. LOCK (Lockout) indicator: Green LED lights when in Lockout mode. Activated by
connection through rear panel DIP switch. Can only be activated when the front panel
LOCAL/REMOTE switch is in the REMOTE position. Once the Lock function has been
activated, it disables LOCAL control for all output control functions except the AC power
switch, which remains under front panel control.
The following indicators will be illuminated only when the optional GPIB controller is installed:
18. ERR (Error) indicator: Red LED lights to signal a GPIB programming error has occurred.
19. SRQ (Service Request) indicator: Green LED lights to signal GPIB service request by
the supply.
20. ADDR (Address) indicator: Green LED lights when the unit is addressed by a remote
controller.
2.4.2 Rear Panel
Refer to Figure 2–2 or Figure 2-3 (depending on the model) and the descriptions below.
