HB Products HBOC Instruction Manual

OIL MANAGEMENT SWITCHES
Instruction manual HBOC and HBOR both mk1 and mk2 versions.

Introduction

The sensors are designed for
control of oil levels in gas HBOC
and in Liquid ammonia HBOR
HBOR will also be useable for
measuring water in oil.
Both sensors can control a level
based on a single switch. These
sensors replace the common
mechanical float and the two-
switch solution where a minimum
and maximum level switch is used
for controlling the level.
The difference between mk1 and mk2 is the output on the cable.
•
HBOC/C and HBOR/C has 24 VDC max 24 W output on the cable
•
HBOC/C mk2 and HBOR/C mk2 has 24 V AC/DC max 24 W output on the cable
Mk2 version are labeled mk2. Mk1 versions are not labeled mk1
The sensors share the same tool and technology, and they can be setup for these 4 modes:
Compressor
For compressors and similar solutions where oil is constantly consumed or removed, the switch can
open a valve which fills up the oil reservoir. The HBOC is used.
Separator
For oil separators and similar solutions where oil is constantly added, the switch can open a valve
which drains up the oil reservoir. The HBOC is used.
Switch
As a normal oil switch which can be configured to any oil type and temperature by changing the
calibration
Oil return
For control of oil pots and suction accumulators where oil, liquid ammonia and ammonia gas can be
present. This application is like oil separator, but this switch can handle the liquid ammonia. The
HBOR is used. The switch is also capable of detecting water in oil - if the water separates.
