Input #1 (IN1) Setup

IN1 Input Configuration
This parameter determines the operating mode of input 1 (IN1)�
• Mode 1: Output 0% When IN1 Low
When the IN1 input is at an electrically low state or wired to
the unit’s common, the GSDA-DP-S will force its output to 0%�
Once the IN1 input returns to an electrically high (+5V) state
or allowed to float disconnected, the output will once again
correspond to the display value�
• Mode 2: Output 0% When IN1 High
When the IN1 input is at an electrically high (+5V) state or
allowed to float disconnected, the GSDA-DP-S will force its
output to 0%� Once the IN1 input returns to an electrically low
state or wired to the unit’s common, the output will once again
correspond to the display value�
• Mode 3: Output Setpoint When IN1 Low
When the IN1 input is at an electrically low state or wired to
the unit’s common, the GSDA-DP-S will force its output to a
percentage which corresponds to the programmed jog setpoint,
parameter 31� Once the IN1 input returns to an electrically high
(+5V) state or allowed to float disconnected, the output will
once again correspond to the display value�
• Mode 4: Output Setpoint When IN1 High
When the IN1 input is at an electrically high (+5V) state or
allowed to float disconnected, the GSDA-DP-S will force its
output to a percentage which corresponds to the programmed
jog setpoint, parameter 31� Once the IN1 input returns to an
electrically low state or wired to the unit’s common, the output
will once again correspond to the display value�
• Mode 5: Output 100% When IN1 Low
When the IN1 input is at an electrically low state or wired to the
unit’s common, the GSDA-DP-S will force its output to 100%�
Once the IN1 input returns to an electrically high (+5V) state
or allowed to float disconnected, the output will once again
correspond to the display value�
• Mode 6: Output 100% When IN1 High
When the IN1 input is at an electrically high (+5V) state or
allowed to float disconnected, the GSDA-DP-S will force its
output to 100%� Once the IN1 input returns to an electrically
low state or wired to the unit’s common, the output will once
again correspond to the display value�
• Mode 7: Lock Set Point when IN1 is Low
“LOC” is displayed when one of the front panel buttons is
pressed with IN1 in an electrically Low State� Program by
bringing IN1 terminal P3-9 to electrically High state or allow IN1
to float when disconnected from Common terminal P3-11� Enter
Program Mode, Select Parameter 30, Press Enter, select value
item 7, Press Enter again�
Note: (Select a value 1-6 to Exit the LOCK Set Point, then press
enter) Select Parameter 0 and press enter to Exit Program Mode�
Activate for the new changes to take effect by cycling AC power
Off/On�
31
IN1 Setpoint
When the S1 configuration, parameter 30, is set to one of the
setpoint (jog) modes (modes 3 or 4), this parameter defines the
jog setpoint in display units� This parameter is always set in
display units�
