The Bijur SM-AC Control Timer
The Bijur SM-AC is a programmable lubrication control timer from Bijur Delimon that automates lubrication cycles by running a pump for a set time and then idling for a set time. It offers four operating modes to match different lubrication system configurations and feedback options. For a broader explanation of how these systems work, see our guide to centralized lubrication systems.
Official Specifications
- Versions: 22361-E2 is the 110 VAC controller, 22361-E1 is the 220/230 VAC controller, both 50/60 Hz.
- Enclosure rating: IP-55 with a liquid-tight connector.
- Fault relay contact rating: 30 W at 220/230 VAC.
- Fault-switch terminal: normally open fault contact, 1 A maximum; terminals A0-A2 are NO, A0-A1 are NC.
- Temperature range: -20 to +55 C.
- Weight: 0.3 kg.
- Audible alarm: beeps when any fault occurs.
The Four Operating Modes
- Mode d1, timer control: The system runs on programmed run and idle times. It suits systems without pressure or cycle feedback switches and provides low level alarm only.
- Mode d2, pressure control: Monitors a pressure-switch input and generates a fault if the required pressure confirmation is not received within the monitoring period. It suits injector systems.
- Mode d3, cycle control: Monitors a cycle-switch input and verifies the programmed lubrication cycles complete within the monitoring period. It suits progressive systems.
- Mode d4, pulse control: Pulsed output operation using programmed pulse-on and pulse-off times. It suits pneumatic systems.
Programmable Parameters
- RUN time: 1-999, selectable in seconds, minutes, or hours.
- IDLE time: 1-9999, selectable in seconds, minutes, or hours.
- MONITOR time: 1-999 seconds.
- Run cycle count: 1-999 cycles.
- Pressure count: 1-99.
- PULSE ON: 1-99 seconds.
- PULSE OFF: 1-99 seconds.
- HOLD PRESSURE: 1-99 seconds.
Time units are selectable in seconds, minutes, or hours where stated for RUN and IDLE times.
Fuses and Fault Wiring
The 110 VAC version uses a 3 A fuse, and the 220/230 VAC version uses a 2 A fuse. Replacement fuse part numbers are 31076 for the 110 V fuse and 31076-6 for the 220/230 V fuse.
For fault-switch terminal wiring, terminals A0-A2 are normally open, and A0-A1 are normally closed. The fault contact is rated for 1 A maximum. The audible alarm beeps when any fault occurs.
Matching the Controller to the System
Mode d1 timer control works for systems without pressure or cycle feedback switches. Mode d3 cycle control pairs with progressive distributors such as the SSV progressive distributor. Mode d2 pressure control suits pressure-switched injector systems. Dual-line valve banks run under timer control, including DD and DM dual-line distributor valves.

Frequently Asked Questions
What is the Bijur SM-AC?
The Bijur SM-AC is a programmable lubrication control timer that automates pump run and idle cycles. It offers four operating modes to match different lubrication system types and feedback configurations.
What voltages are available?
The 110 VAC version is part number 22361-E2, and the 220/230 VAC version is part number 22361-E1. Both versions operate at 50/60 Hz.
What enclosure rating does it have?
The SM-AC has an IP-55 enclosure rating with a liquid-tight connector. This rating protects against dust and low-pressure water jets.
What are the four operating modes?
The four operating modes are d1 timer control, d2 pressure control, d3 cycle control, and d4 pulse control. Each mode matches a different lubrication system feedback method.
Which mode suits a progressive system?
Mode d3 cycle control suits a progressive system because it monitors a cycle switch. It verifies that programmed lubrication cycles complete within the monitoring period.
What parameters can be programmed?
Programmable parameters include run time, idle time, monitor time, cycle count, pressure count, and pulse settings. Run and idle times can be set in seconds, minutes, or hours.
What fuse does each version take?
The 110 VAC version takes a 3 A fuse, and the 220/230 VAC version takes a 2 A fuse. Replacement fuse part numbers are 31076 and 31076-6.
How does the fault output work?
The fault relay contact is rated 30 W at 220/230 VAC, and the fault contact is rated 1 A maximum. Terminals A0-A2 are normally open, and A0-A1 are normally closed.
Does it signal faults audibly?
Yes, the SM-AC beeps when any fault occurs. The fault relay also signals externally through the fault contact terminals.
