OUTPUTS CONFIGURATION SUB-MENU SCREENS
Output n Configuration - Up to 9 outputs listed. Any a lready used show as “Assigned” but can be
changed. If “Digital” is shown, the output is driven directly via a digital input (see input configuration).
Relevant screen sequences repeat for outputs fitted. Press D + R to return to Configuration Menu
Linear Output n Type w Set the desired type for any linear outputs fitted. From: 0-5, 0-10,
1-5, 2-10V & 0-20, 4-20mA or 0-10VDC adjustable transmitter PSU.
Adjustable 0-10V
Transmitter PSU n w Sets the voltage required if linear output n type is 0-10VDC adjustable
transmitter PSU.
Output n Usage w Sets the use for the output. From: Loop 1 or 2 Primary / Secondary Power;
Logical OR or AND of Alarms & Profile Events (direct or reverse acting);
Retransmission (of loop 1 or 2 effective setpoint, Input 1 or 2 process
values). Choices offered are appropriate for the output type fitted (e.g. only
linear outputs can retransmit).
OPn OR Selection w When an output usage is set for logical OR of alarms & profile events, this
selects the alarms or events to be OR’d. Press U or D to select ☑ or
deselect
☐ Alarms 1 to 7; Events 1 to 5; PR (Profile running); PE (Profile
Ended). Direct outputs turn on, & reverse outputs turn off according to the
selected logical OR combination.
OPn AND Selection w When an output usage is set for logical AND of alarms & profile events, this
selects the alarms or events to be AND’d. Press U or D to select ☑ or
deselect
☐ Alarms 1 to 7; Events 1 to 5; PR (Profile running); PE (Profile
Ended). Direct outputs turn on, & reverse outputs turn off according to the
selected logical AND combination.
Output n Latch
Enable w If enabled, an output will remain latched ON even if the condition that
caused it to be on is no-longer present, and remains latched even if the
instrument is powered off-on. The output latch must be reset to turn it off.
Note: An output cannot reset if the condition that caused it to
turn on is still present.
Output n Lower
Retransmit Limit
w
The displayed value at which the retransmission output reaches its
minimum level (e.g the display value when a 4 to 20mA retransmission
output is at 4mA). Adjustable from -9999 to 9999.9. The output is at its
minimum below this value. Above this value, it rises linearly in line with the
displayed value to reach its maximum at the Upper Retransmit Limit display
value.
Output n Upper
Retransmit Limit The displayed value at which a retransmission output will be at its
maximum level (e.g. the display value when a 4 to 20mA retransmission
output is at 20mA). Adjustable from -9999 to 9999.9. The output is at its
maximum above this display value. Below this value, it falls linearly in line
with the displayed value to reach its minimum at the Lower Retransmit
Limit display value.
ALARM CONFIGURATION SUB-MENU SCREENS
Alarm n Configuration - 7 alarms listed with any already used shown as “Assigned”. Relevant
screen sequences repeat for each alarm (n = 1 to 7). Press D + R to return to Configuration Menu
Alarm n Type
w Sets the function of alarm n from: Unused; Process High; Process Low;
PV-SP Deviation; Band; Control Loop; Rate Of Signal Change per minute;
Input Signal Break; % of Recorder Memory Used, Control Power High,
Control Power Low.
Alarm n Source w The signal source of Alarm n from: Input 1, Input 2 & Auxiliary Input A;
Control Loop 1; Control Loop 2; Loop 1 Primary or Secondary Power; Loop
2 Primary or Secondary Power
– auxiliary input A is only possible if fitted
and the alarm type can only be input signal break.
