Description:
The batch length is specified in hours, or optionally in the number of packs if a PEC is fitted. The
batch length represents the amount of production statistics that will be accumulated, before they are
transmitted down the serial link to a printer or computer, and then reset to zero.
Press the [ENTER] key, and then the [▲] and [▼] keys to adjust the batch length as necessary.
Scope:
00.00 to 24.00 for timed batch interval
0 to 9999 for pack batch interval
Default:
01.00 for time.
Notes:
Batch reports must be enabled in the Report Options menu for this menu entry to appear.

Description:
This facility can be used to synchronise the start of the batch to a particular time of day. For example,
if hourly batch statistics are required starting from 6.30pm, then the Batch Length would be set to
1.00 hour and the Batch Start to 18.30 hours. This would mean that the batch statistics would be reset
and transmitted down the serial link every hour at half past the hour.
Press the [ENTER] key, and then the [▲] or [▼] keys to adjust the batch start time.
To turn the start time facility off, so that batch statistics are reset and transmitted at multiples of batch
lengths after the batch starts, set the start time to 00.00.
Scope:
00.00 to 24.00. 00.00 will disable this facility.
Default:
00.00
Note:
This menu entry will only appear when Batch Reports are enabled, and the batch units are in terms of
time.

Description:
Clearing a system fault will turn the system fault LED and Fault relay off, providing the fault is no
longer occurring. If the fault is active, ie. still happening, then the system fault will immediately come
back putting the fault LED and relay back on.
System faults are usually an indication of a serious malfunction with the equipment, and must
therefore be investigated promptly. Refer to the section on Error/Fault Logging for full details about
system faults, and what to do if you have one on your system.
Press the [ENTER] key to clear any system faults.
Notes:
On failsafe systems, the fault relay is typically wired into the conveyor or reject so that no product
can pass down the line in the event of a system fault.
Clearing the faults as described here will reset the LED fault indicator and the internal fault relay, but
the details in the fault log will not be cleared. These are maintained by the system for Loma Customer
Service Engineer reference.

Description:
This value is automatically derived during a calibration cycle, and should therefore not normally
require adjustment: only alter the value if advised to do so by a LOMA Service Engineer.
Press the [ENTER] key to view the compensation and signal level values; the [▲] and [▼] keys to
adjust the compensation value. The compensation value is displayed on the left hand side of the
display, and the signal level on the right hand side.
Scope:
-65535 to 65535
Notes:
This menu position is only accessible if the Manual Setup menu has been enabled in the User Options
menu.
The calibrate LED will illuminate whilst the compensation value is being adjusted.
For more information about what the compensation value does, please refer to the Principles of
Operation section.

Press the [ENTER] key to move into this menu.
Notes:
Once the Configuration menu has been entered the detector will stop detecting and the Run Detect
LED will go out.
If the detector suffers from memory corruption it will reset itself automatically into the top of this
menu showing the message +NOT DETECTING+. Under these circumstances please consult your
nearest LOMA Service Centre.
If BATCH mode operation for PV Test is selected then the Configuration menu cannot be entered
unless the PV Test operation is turned off in the User Options menu.

Description:
The delay is the time taken for a contaminated product to travel from the detector head to the reject
point, or from the photo eye (PEC) if one is fitted to the system.
Press the [ENTER] key, and then the [▲] or [▼] keys to adjust the reject delay time.
Scope:
The minimum time it takes the system to respond to a contaminant to the time it takes the pack to
travel 122 times the detector coil gap if a PEC is not fitted, or 240 times the pack length if a PEC is
fitted.
Default:
Minimum.
Note:
For vari-speed systems the delay should be set at the fastest line rate to guarantee that the reject
operates quickly enough.

Description:
Pressing the [ENTER] key will cause the reject device to be “turned off” so that no product is
rejected, even if contaminated. This operation is not recommended, but may be useful at times of
maintenance.
Notes:
Once the reject device has been disabled, this menu item is replaced by the Enable Reject command.
This menu entry will not appear if the Reject Out of Run option has been enabled in the User Options
menu.
The Run Detect LED will go out when the reject is disabled and a run error will be logged (causing
the run error LED to illuminate and the auxiliary relay to be energised if it has been set to act as an
error indicator). If the auxiliary relay has been set to act as an in-run indicator, then it will be de-
energised when the reject is disabled.

Description:
In certain applications, such as ones where the detector is subjected to a high degree of vibration, the
detector may not choose the optimum calibration setting for dry products during a calibration cycle.
In cases such as these it may be necessary to set this setting to “YES”, so that the detector is forced to
work in the Dry mode (see Working Mode of Detection in this section).
Press the [ENTER] key, and then the [▲] or [▼] keys to adjust the setting.
Scope:
YES or NO.
Default:
NO.
Note:
For pharmaceutical pill detectors this should be set to YES, unless the pill is known to have some sort
of conductive additive such as iron.

The dwell is the time, or distance in vari-speed systems, that the reject device is activated for once the

Scope:
0.025 to 49.995 Seconds (0.005 to 9999m vari-speed).
Default:
0.025S (0m vari-speed)
Note:
For vari-speed systems the dwell time should be set at the slowest line rate to guarantee rejection of
all contaminated products.

Description:
The false threshold is used to identify metal test samples being used which are greater than those
specified for testing.
A product relative false threshold default value is generated for each product position. The value can
then be manually adjusted to achieve precise control.
Any signal generated which exceeds the false threshold value will be displayed as a “FALSE
CONTAM” (false contamination) and does not count towards a successful test.
Press the [ENTER] key, and then the [▲] and [▼] to adjust the false threshold value.
Scope:
0 to 99990
Default:
Twice the default working threshold
Notes:
This entry only appears if PV Test is enabled in the OPTIONS menu.
The manual adjustment increment or decrement is in steps of 10 units.
The value set cannot be lower than the generated working threshold.
