7.0 Options, Replacement Kits
There are numerous replacement part numbers mentioned throughout manual that can be ordered.
7.1 Freeze Mode Option - PN 57778
NOTE: This option may not be used with APC 4000 or APC4001 interface option.
See “Freeze Mode Option Wiring” on page 11 for wiring information.
This mode, often used for testing pressure switches, is an edge triggered input signal that will “freeze” the last
display update for approximately five seconds, as soon as, either opening or closing of a switch contact between
an active input and RETURN. However, while the display is in the freeze condition it will not respond to another
contact transition.
Specifications:
• The Freeze input will “freeze”
the display for approximately five seconds on the rise and fall time of the
input (edge not level triggered) and is “non-retriggerable”.
• Input pulse > 100 ms required to guarantee detection.
• The freeze will “freeze”
the 6 digit numeric and LED bar displays in whatever mode it is in (i.e. Normal,
Max or Min mode).
• During the “freeze”
the Front Panel Keys are inactive.
• Inputs are a +5 VDC logic level. Sinking current approximately 0.5 mA.
7.2 Peak Hold Option
UPS3000[][]A, UPS3000[][]B, UPS3210[][]A, UPS3110[][]A, UPS3110[][]B, UPS3210[][]B use PN 57775
UPS3000[][]C, UPS3210[][]C, UPS3210[][]C use PN 57798
NOTES: Recommended factory installed option requires software configuration.
This option may not be used with APC 4000 or APC4001 interface option or MIN/MAX Option.
When model is Absolute or Gage front panel switch selectable, “CONV” button is replaced and therefore, the required
conversion must be set through reconfiguration. See “Engineering Conversion with PEAK HOLD or MAX/MIN Option” on
page 12 for applicable method to change to required conversion.
This option retains the last highest pressure reading and stores it in memory.
It can then be recalled upon demand at any time provided:
1. The unit has not been powered down (power removed).
2. The reset button has not been pushed.
3. The range select switch has not been changed to another range.
